My guess is the kind of careless people who don't check for cyclists tend to be the kind that throw their doors wide open in one movement, so while this doesn't hurt, it gives cyclists a split-second's warning at best.
- adhesive_wombat 5y agoCertainly, it gives a cyclist a split second if someone opens a door suddenly. That's not what it's really for - nothing can prevent that. For people opening a door sensibly (most people), it gives a unambiguous warning that a door is ajar ahead maybe 5 or 10 seconds before the door opens more. In the dark, where reflectors work, that's a lot more than you might get if you don't notice the door is ajar.
