You can build and set off bombs. It's just heavily regulated. However, many people haven't really consented to driving. They drive out of necessity. Where they live and work is only marginally in their control and there are no other transport options. When I was poor, I would have loved to not have to pay for insurance, gas, maintenance, and the vehicle itself. I couldn't really afford it. But without it, I couldn't get to work to eat. There weren't other options. When I made a little more money I could finally afford to live close to work and public transport was an option. The trip was 5 minutes by car, over an hour by bus. I'm on board for heavily regulating driving and shifting that danger assessment as you suggest. But first I think there is a moral obligation to provide alternative modes of transportation. (This should not be interpreted as excusing drivers from their obligation to be skilled and safe.)
