Don't be daft. I'm not going to die falling off my bike when it's not even moving. All I had this time was a bruise on my bike; last time I had cuts and scrapes. If my bike had been moving, it might have been nasty; but I'm not going to hurt myself badly falling from a stationary bike.

Besides, (a) I like being able to accelerate fast from a standing start with my SPDs, and (b) the SPDs and pedals cost £95, and I'm not going to waste that. All I need to do is learn to (a) unclip in a hurry, and (b) strike the right balance between not unclipping enough, and unclipping too much.
