Here is a number: $103,600.
That’s what a Nokia executive named Anssi Vanjoki paid in 2002 for going 75 km/h in a 50 zone on his motorbike. Not a typo. Finland calculates traffic fines from income, and Vanjoki had a lot of it.
Here is another kind of number, the one that never makes headlines: the $200 fine that means a missed rent payment. The $80 ticket that turns into a suspended licence, which turns into a lost shift, which turns into worse. Nobody writes an article about that one. It just happens, quietly, to somebody, most days, in most cities.
Same infraction. Same law. Two entirely different planets, depending only on what was already in your bank account before you broke it.
Innovation is not always a device. Sometimes it is a change in what a system counts. Sometimes it is a different unit of consequence. This is the first in a new Innovation Toronto series exploring real openings — scientific, civic, technological, social — that ask not only what might be built, but what might be changed by building differently
Money is either punitive or meaningless, depending on circumstance. There’s no version of a flat fine that’s fair to both people in that sentence, because the number never changes and what it costs always does.
Finland’s already found half an answer. Since the 1920s, fines there scale to income — divide daily earnings roughly in half, multiply by how far over the line you were. It’s why Vanjoki’s ticket has an extra zero yours wouldn’t. Several other countries have followed since. It works, more or less, at making the sting proportional instead of arbitrary.
But it has a quiet flaw: it needs your income defined, and defined income is exactly the kind of thing that bends around a good accountant. The same resources that help someone win almost any other dispute also help them argue their fine base down. Money finds its way back in through the paperwork.
So here’s the wonder: what if the unit wasn’t money at all? What if it was time?
Everyone has the same twenty-four hours in a day. Not the same value in every hour — an hour costs a surgeon differently than it costs someone between jobs — but you can’t hide your hours the way you can restructure your income. There’s no offshore account for Tuesday afternoon.
A fine paid in hours spent on public projects. Not community service as an afterthought for people who can’t pay — the actual, default currency, for everyone, rich or not. Fix the trail. Paint the community centre. Clear the ditch that floods every spring.
Here’s where I think the emphasis actually wants to sit, the longer I turn this over: leveling the fine might not be the important part at all. The important part might be the stranger.
In 2022, Raj Chetty and a team of researchers analyzed 21 billion Facebook friendships, mapped by zip code, against IRS income records — the largest study of its kind ever attempted. They were hunting for what actually predicts whether a poor kid grows up to escape poverty. They tested the usual suspects: school quality, family structure, neighbourhood inequality, racial segregation. One factor beat all of them, by a wide margin — how many of a child’s friends, growing up, came from a different economic class than they did. They called it economic connectedness, and it was strong enough to make most of the traditional explanations look almost beside the point.
The detail that matters most for this idea: it wasn’t proximity doing the work. Living near wealthier people, attending a well-funded school, sharing a zip code with a mixed-income population — none of that moved the needle much on its own. What predicted mobility was actual interaction. Knowing them. Being friends with them. Contact, not co-location.
Which is precisely the shape of a work crew, and not the shape of a mixed-income neighbourhood where two households share a postal code and never speak. Social psychologists have understood the mechanics of this since the 1950s — contact between people from different backgrounds only closes distance under specific conditions: equal status, a shared task, real cooperation, something institutional backing the setup. A fine served shoulder to shoulder with a stranger hits all four by accident, just by being built the way it’s built.
We already run one small, unremarked version of this, so quietly most people never notice how strange it actually is: jury duty. One of the last places in modern life where the law simply doesn’t check your tax bracket — a surgeon and a warehouse worker, one vote each, deliberating as functional equals because the summons doesn’t care what either of them does for a living. Nobody thinks of jury duty as a social experiment. It’s been running as one for centuries.
Here’s the speculative part, and I want to flag it clearly as exactly that: nobody’s built this at the scale I’m imagining, so nobody actually knows what it would do. But if Chetty’s finding holds — that interaction is the active ingredient, not proximity — then a fine paid in shared hours isn’t only a fairer punishment. It’s a delivery mechanism for the single strongest lever on mobility researchers have found yet, running quietly in the background of ordinary civic life, asking nobody to volunteer for anything.
Traffic offences might be the ideal entry point, for a reason worth saying out loud: speeding doesn’t sort by income the way most studied offences do. Rich people speed. Poor people speed. Nearly everyone does it eventually. A system built around it wouldn’t only reach people already struggling. It would, sooner or later, reach almost everyone — including people who’d otherwise go their whole lives without spending an unstructured afternoon anywhere near someone outside their own bracket.
It wouldn’t happen automatically, and that’s worth being honest about too. A crew working in parallel instead of together, or hours that could somehow be bought out or delegated, wouldn’t produce any of this — it would just be community service with extra paperwork. Chetty’s finding is specific: contact, not co-location. Whatever this became would have to be built for people to actually work together, not merely occupy the same site. And probably not from one afternoon, either — what might really matter is the ambient, repeated, unremarkable fact of it happening across a whole population, year after year. Less a single dramatic fix than a slow kind of infrastructure for something that’s been quietly going missing from a lot of people’s lives: an ordinary reason to spend real time with someone whose life doesn’t look like yours.
A fine takes something and gives nothing back. A finished bench in the park is still there next spring. That’s not nothing either.
The honest catch: cities collect real money from fines, and some of that would go away. For most places it’s a smaller number than you’d guess — a rounding error against the total budget. But there are exceptions, and they’re instructive ones: towns that came to lean on ticket revenue so heavily it started shaping who got pulled over and why, not how safely anyone was driving. Losing that particular kind of money isn’t really a loss. It’s removing the thing that was bending the whole system sideways in the first place — the bad kind of sideways, not the good kind.
None of this is proven, and it hasn’t been tried anywhere near the scale I’m describing. Maybe it wouldn’t hold up. Maybe the surgeon’s hour really is worth arguing about, the same way the accountant’s income statement is now.
Right now, the fine a wealthy person pays and the fine a poor person pays for the identical mistake aren’t measuring the same thing at all. One is asking can you afford this, and pretending it’s asking did you do this. Time doesn’t have that problem. That’s reason enough on its own.
But it’s not actually the reason I keep coming back to this. It’s the stranger with the shovel. It’s the version of a place where an ordinary Tuesday afternoon, for no noble reason whatsoever — just because you were doing twenty over on your way to work — puts you next to somebody you’d otherwise have spent a whole life quietly managing not to meet.
I wonder what that would do to a place, given a few decades. I wonder if we’re only one generation of speeding tickets away from finding out.
