Re: As an aside, one thing that annoys me about my car
Cruise control is hopeless, speed limiters are a far better system. The moment I take the foot off the pedal, the car slows down. I use it all the time, set the limit to a safe speed just below the speed camera trigger speed and if necessary, I can push the pedal down to override the limiter.
The driver is still the speed limiter and needs to set an upper limit. The car won't keep the speed without a constant signal to do so, though.
