Some interesting stuff here, including links to more studies showing similar results in different countries.
The summary is that the reason motorists break more laws is that speeding is so common.
I don’t think this is because motorists are all evil and cyclists are all saints. Probably, the reason motorists break speed limits is that it can be relatively difficult to keep cars below the speed limit. It’s all too easy to absentmindedly speed up. It’s also, perhaps becuase of this, widely seen as socially acceptable to break the speed limit (speaking anecdotally).
One interesting thing here, which may not surprise regular readers of Fuck Cars, is that better cycling infrastructure leads to less lawbreaking by cyclists. As is often the case, it’s the design of roads and cities that changes behaviour, not abstract appeals to road users to be sensible!
Please tell me what exactly a helmet in a car will do for you, unless you are travelling well over 200 miles per hour? Seatbelts already hold the torso in place, preventing one from slamming their head into the steering wheel, dashboard, or windshield, and the airbags already absorb the energy and arrest the unrestrained body parts, such as the head.
You would have to be travelling fast enough to outpace the airbags, which typically deploy at around 200 miles per hour. You wanna know why professional race car drivers wear helmets? Because they don’t have airbags.
Because all those safety features don’t prevent cars from being the place you’re most likely to get a traumatic brain injury.
It’s quite illustrative how furious you are about this. If you read what I’m saying properly, you’d see that I don’t think people in cars should wear helmets. My point is that the arguments for doing so are just as good as they are for cyclists, i.e., not at all.
