Yeh we get the same here. Add a bit of rain to the peak hour traffic and everyone starts panic braking.
The F3 is particularly fun. The traffic flows at the posted "110 km/h" but the cars space themselves like its a 50 zone. You've got to have lightning fast reflexes when the panic braking domino effect snakes itself towards you.
The good thing about the bike is you can see over the top of the traffic.
