Sorry guy's, but you're both complete idiots.
I'm not talking about crashing and paying for barriers and car repairs, we can all manage that. I'm talking about the time a hose splits and coolant leaks out. You pull over immediately, but a car spins and maybe a biker comes down at high speed (I've seen it happen a lot!). The crash causes the biker to break something badly, or worse, paralises them (lets not think of death). No insurance? You are paying for them for the rest of your life as well as a nice visit from the Polizei.
Think it doesn't happen? think again! I've been in a car with 3 other CS members when a Focus RS spat a pipe out. I saved the spin, and we pulled over straight away but even with us waving people down a biker still came down. Who'd be responsible? The focus driver!
Plenty about this on Northloop forum
