Drivers who willfully block the box get away with it time after time after time. That needs to change
It's time to increase fines from $85 to $500 for blocking the box on any and all intersections. Doing so would make it's safer for everyone including pedestrians.
If it's anything like in the US sometimes the intersections are screwed up and you can sit at a light through a few greens without moving because the road you need to go on gets filled by turning lanes before the light turns red and fills up before yours is green again.
Which is what makes the next people feel like they have to pile in to the box or they'll never get anywhere.
It's the same where rights are allowed on reds. If you don't pile into the box and there is a line of cars waiting to make a right, someone WILL steal that spot when it opens up just past the box, because people are selfish assholes, full stop.
