No. If you need bailing out of date in such manner.... Why not just tell them it's not working? The other person also put some time into it—possibly more. smh
Have you ever crashed into another bicyclist and you both took a disastrous tumble?
I was once hauling ass (probably 20mph) home from work and this guy on another bike pulled out from between parked cars after the intersection while not paying attention... I slammed full force, no brake, right into his front tire! Ever seen a pretzel? That's what it almost looked like. Both of us weren't hurt.
