Erm..... There is a big hole here GB. What if the anti-drink/phone systems developed a fault and did allow someone over the limit to drive or to use a phone....who would then be responsible if there was an accident?
The car makers?
If they have to carry the responsibility for the acts of the drivers they simply wont fit these devices, and if they become a legal requirement they will add huge costs to cars and people simply wont buy them, and of course someone will ultimately find a way round them.
The drivers? If they are going to be held responsible despite the fitment of these devices in their cars, the question then is, why fit them in the first place.
It will become a legal minefield and everyone will be blaming each other.Therefore personal responsibility should never be taken away from drivers and placed on the car makers or anyone else for that matter. Consider this, just about every car sold in the UK can top the legal limit of 70mph. Is it the car makers fault if someone is caught speeding? Another consideration, if someone is caught using bald tyres is it the tyre makers fault?
More emphasis on driver education and tougher penalties, both as punishment and a deterrent, its the only fair way and if you notice that is exactly what has happened recently with mobile phones. Furthermore if the incident rates related to mobile phone use behind the wheel don't drop the penalties will be increased again
