Jesus, its a visit from the oldest road safety fallacy in the world.
Making cars/roads incredibly dangerous to make people drive slower DOESN'T F*CKING WORK.
It's the same as trying to sort out your finances by earning less, because then 'you'll have to spend less'. It's utter nonsense.
The VAST majority of accidents are just that, accidents, NOT people driving round going "hey, I've got airbags, I'll drive at 130mph into this wall".
Putting spikes onto steering wheels or even removing the current safety features will only kill many hundreds of thousands of people involved in minor accidents. We have airbags, seatbelts etc because they DO work. The accident rate (and injury/death rate) in all developed countries has been dropping significantly over the last 50 years, both in absolute terms and even more so per vehicle mile, incredible considering the increasing density of traffic and the vastly increased speeds both achievable by modern vehicles, and the fact that drivers today spend more time driving, and driving faster than ever before.
When the M1 first opened (without any speed limit BTW) the 'average' family car would struggle to achieve 70mph. To do 100mph you would need a 'fast car'. Today the average hatchback can happily do 120mph all day, and LOTS of people do (over) 100mph every single day. Road accidents have still been dropping dramatically.
This is because (generally) we have had sensible policies of making our cars and roads SAFER (including where that enables higher speeds); country lanes have been replaced with motorways, third lanes have been removed, hazards have been signed, airbags fitted etc.
DO NOT try to f*ck up this good trend up by assuming that every accident is caused by some evil driver behaving recklessly. It's not any more true of road accidents than it is of workplace accidents, home accidents or anything else. By your logic, machine guards n factories should be replaced with lethal electric fences, because then workers will be REALLY careful about not touching the machine! It's absolute nonsense.
