Cars kill more than 100 people annually. If punitive measures are required you should start with drivers.
See for yourself.
I suggest :
1. Annual driving test, eyesight test and physical.
2. $5000 a year for driving license.
3. Speed limit reduced to 40kph max throughout the road network.
4. Max 1000cc petrol engines and the equivalent HP rating for hybrid/electric vehicles.
5. Age cut off of 65 years.
