I'd bring in strict liability for the larger vehicle in all accidents, only to be overturned with hard evidence. Basically make it prohibitively expensive to insure a motorised vehicle unless you have integrated cameras / black box / GPS speed / location tracking. Death penalty for people driving without insurance. Start with HGVs and bring it to other vehicles later.*** Automatic bans for all accidents whether you are at fault or not.*** (Obviously much shorter for the innocent party than the guilty)
Annual theory tests. 5 yearly driving tests.
Much tougher penalties for bosses of companies who make their drivers work too hard / fast, whether the drivers crash or not.
As much as anything the problem is that everyone is in a hurry, both the driver and the cyclist going up the inside.
Wow. I'm getting out of here.*
