Certainly it doesn’t happen very often, so whilst manufacturers need to design products that are safe and childproof the idea that they can be made safe for the mentally challenged, the autistic and the very stupid is questionable because would those without these problems be prepared to pay for the extra safety measures?
I suspect the answer is ‘no’ but the manufacturers should survey people to see what the traffic will bear.
The response times of the emergency services are a different matter and should be improved proportionately.
Parents and guardians should be held more responsible but there is a limit to the degree of featherbedding and safety one can employ before it becomes counterproductive. With cars for example, independent suspension, synchromesh on all 4, 5 or 6 gears plus reverse, parking cameras, side impact protection, airbags, crumple zones, positive rear ends, intelligent suspension, anti-slip differentials should all make people safer yet independent research shows that people feel able to drive faster, thus negating the effects of the safety measures.
Also as more and more gadgetry and electronics are added, there is a greater and demonstrable risk of fire and as more people get driving licences and buy cars the intelligence level of drivers falls because the authorities are not prepared to make the driving test more rigourous because of the possibility of more failures and thus fewer drivers who can be taxed.
