Big brother has his hand on your throttles UK !

[jumpy]

Stupid idea if you ask me - the system will never be smart enough to react/take into account changing road situations a driver might find him or herself in. As such, having the nanny-throttle take control away from the driver at a critical moment could very well cause an accident, not prevent one.
A much better use of the london transport budget would be to better train their drivers accordingly, coupled with the use of mechanical limiters (already in use on articulated lorries* and buses) which limit the vehicles top speed to a fixed variable. Stiffer penalties for drivers who break the rules would be more efficient too.


* the problem we have in the UK is lorries from the continent which do not respect the laws regarding speed limitations for vehicles of a certain weight and size, and the Tachometer laws regarding the amount of time a driver is allowed to be behind the wheel driving without a rest. There have been a number of fatal rta's where this was to blame.
