So you like the fact that the police know exactly where and when you drove? Because the licence plate tracking cameras require that, you know.

Also, the notion that there is some universal speed limit that makes driving safe on a particular road is silly.

Two scenarios with speed limit of x: 1) sunny day, brand new porsche, new tyres. I'm driving at a sped of x+5 2) windy, snowy day, nissan sunny from the 80s with almost worn out tyres. I'm driving at x-5

Pick the safer one. I doubt anyone would think option 2 is safer, yet 1 is illegal and 2 is perfectly fine.
