To me, it DID look like the bike was a 'bit' fast...but there seemed to be some confusion on the part of the cage driver..he/she started the turn then slowed almost to a stop. Saw the bike, 'wondered' about it, almost stopped, blocking the bike's path the finished it off by rolling out.
I try to eliminate the 'confusion' of these nitwits, when i run across them, by slowing, high beam on, weaving in lane to try to attract some sort of attention behind those dead eyes and keep reading what's going to happen next. The last resort is to aim toward the center line where the car is leaving from, hoping to get around the right side of the car as it pulls away. It's a crap shoot with these a-holes.
