I mean there's no street legal car in the world that can go 420 so you'd probably just get that ticket thrown out. Still have to pay the court cost though which is bullshit.
Where I live, the highway speed limits are 65 and State patrol are always sitting near my house, often ticketing people for as little as 70. I set my cruise at 69. It's nice.
You think. There was an infamous case in Hungary where someone was cited for allegedly going 260 kmh in downtown Budapest. In an old Ford Transit van. While reversing.
The police simply refused to entertain the idea that someone knocked the camera and it made a bad read.
They had to close off the street and demonstrate that the van couldn't get to 260 in reverse.
The most memorable thing of the whole case was the head of the police saying with a straight face "Hungarian traffic laws are not enforced according to the laws of physics", as part of the prosecution argument.
