It's a bit like the sensors on some of the newer big cars on the mirrors that let you know that there is a car in the lane next to you - what's wrong with turning your head to check ??? Some idiot will blame the car for a crash.
My wife has an old school friend that posted on facebook that she had to do a driver awareness course for speeding. Doing 70 in a 50 and blamed it on the satnav as that said 70. No, what's wrong with looking at bloody road signs. Satnavs are usually a good year out of date before any road changes get updated. Time cars went back to basics.
You can also see rear end crashes being blamed on the electronics not stopping the car just because the driver doesn't look. It's like SMIDSY is somehow an excuse. Thats the first thing the driver said to me. My response whilst a nurse had my head held was, what with bright red clothing and those lights...
All this tech is making folk think they don't need to do the basics, like looking twice.
