That's a false equivalence.
The real trick is proper and continual training in the use of any large machine (car) or piece of equipment (gun).
Think about it, anyone operating say, a laminating press, the ones that make all the post-formed kitchen counters and such, will have mandatory competency ratings on a regular basis, yet we allow any old moron into a car with a test a trained ape could pass, and that's it, let the fool loose in a 2 tonne plus killing machine.
It's not though, if you remove the guns all deaths related to them go away.
Same way with cars if you limit the speed all high speed collisions and related deaths automatically go away.
They physically can't happen therefore they are nullified.
It's not a false equivalence, it's just a simple truth of reality.
That being said I fully agree we need much much better driver education and I've said this for many years here and elsewhere because even with a 180km/h limit you can still kill someone quite easily doing something stupid in a 60km or 80 km/h and limiting the speed doesn't make any difference there.
Personally I feel nobody should be allowed to get into a car doing just a theoretical test. It should be a practical course you attend and once passed you are allowed to write the learner's exam and once you've gotten that you can drive on the roads (but no highways) and then you should prep for an advanced driving type course after which you can do your license test or the advanced driving course test can simply approve you as license bearing so you can then apply for the government bit.
Fact of the matter is restricting the top speed will have a net positive effect, just like taking guns away from people will do the same.
And before you assume I'm one of those tree hugging types, I'm a motorcyclist and petrol head and regularly go well beyond the restricted limit proposed because I have years of experience and have done said training and therefore know what calculated risks are involved.
Problem is the lowest common denominators can't make that risk calculation and it's those people we need to scrape off the road, so for the greater good I'm all for it being implemented especially on dinky toy every day cars that people drive simply to get from A to B.
At the end of the day it's about thinking for and catering to the lowest common denominator and those sadly aren't very bright and there are millions of them.
