Car driving is not de-risked at all.
Give yourself 10 seconds and you could come up with 10 ways to save hundreds of thousands of lives each year.
Off the top of my head.
1. 5 point harnesses for all road users. (can't believe it's not done.!)
2. Helmets for everybody in cars. (pain in the bum but hardly too onerous)
3. All cars maximum speed limit 50mph (Not really a big deal)
3. Max limit in town 20mph (moving that way)
4. All cars coated in 6 inches of foam padding. (even banning bull-bars would help)
5. Mandatory annual driving test. (old buggers have never had to take one!)
6. Breathalysers integrated into ignition system. (Obvious)
7. Annual Medicals (expensive but effective)
8. Ban all sports cars (obvious)
9. Ban motorbikes (more obvious!)
10.Mandatory cargo nets for all transported goods in cars.( I have bad memories from a SAR shout to an RTA with kids and a portable amp in the back
)
None of these are in any way technically difficult, yet would have greater or lesser effects on the experience of driving. We choose not to do these things because we have decided that the risk is reasonable without them.
Contrast that with aviation.
You say that my example contrasts the whole world against Shoreham, but that is not the case.
How many air-shows in the last 50 years had an aircraft crash outside the airfield that killed passing motorists?
Where is the hand wringing when a bus crashes and kills 20? Where is the sudden change in rules and regulations governing all road users?
