On a highway you would usually go 80-120 kmh.
No easy way to imagine that kind of speed in a car for most people.
Here are some things and their speeds in kmh:
- human falling at terminal velocity belly down: 200 kmh
- plane right before touchdown: 250 kmh
- f1 racer: 320 kmh
- cannon ball being fired: 3000 kmh
- fastest baseball pitch: 170 kmh
Anyway, he probably has only a few more times of that before he crashes and instantly dies (and probably kills a bunch of people)
Depends on how much you care about stealth.
