For a cyclist sitting upright (CdA of .5) but with good tires and pavement (Crr of .0035), it takes about 120W to hold 15mph on flat terrain. I would agree that this is about the limit for most casual riders. Serious riders with more power typically don't have a problem riding around other bike lane users. What I'm saying is, I don't think the robots are burdensome for the average bike lane user, as far as speed is concerned.
