Personally I chickened out at about 170 kph (my dad's car, so yeah, don't want to get caught doing that in my dad's car hehe), but a taxi driver (in Mallorca, on holiday) thought the car's on the freeway weren't fast enough and decided to drive past them at over 220 kph. That was a bit scary, especially since I'm not sure he was sober

My friend has a video of himself doing > 270 kph on his bike though. Sorry but if you do > 270 kph on a public road you're *** insane
