You can't carry large items on a bike
Cyclists have to ride single file
Cyclists are constantly causing accidents by forcing other vehicles to swerve
Cyclists can damage another vehicle and then just cycle off since they can't be identified (exactly like anyone on foot then)
You could also add that one reason that London roads are too narrow is that their effective width is reduced by having cars parked on both sides. This is a particular arseache if it reduces the road to being 1.5 lanes wide, so cars coming in opposite directions have to queue and wait to get past each other. This is one instance in which cars massively slow down bike journeys.
