anyone who drives at 198 mph on a public road (even on the continent) is a prize fool – the stopping distance is somewhere between 250 and 400m depending on road conditions. One small unforeseen incident at that sort of speed won’t just kill the driver but would probably take out a couple of other road users as well.
You are ok upto 250kmh/150mph on unlimited Autobahn’s (of which there aren’t that many) as you’re still covered by insurance, above there…
Nothing better than passing a car which is doing 150mph, and accelerating away 🙂
