• Not necessarily. First, ban huge pickups from private use (make them commercial licence only); second, tax heavier than 2000 kg vehicles. If you make small, light vehicles the norm you’ll make roads safer for everyone. Crumple zones etc can be made from composite materials and eg glass fiber is cheap, light and durable.

    Remember that an F1 car is surprisingly small and light, yet the driver can walk away from truly awful high speed crashes. We don’t need to mandate firesuits and neck restraint devices for road traffic, but at city and intercity road speeds (in Europe, typically 50 and 90 km/h) a small light car can be reasonably safe.
