Even if you do, the bikes are not going to kill you.

This is not true. It is less likely than with automobiles, but pedestrians are killed by bicycles from time to time. Obviously bicycle-bicycle accidents that happen in traffic are also dangerous.

Yes and people die from drinking too much water too.

Irrelevant to the case of killing other people in avoidable accidents.

Like automobiles, lots of cyclists (and I am one) believe that they are able to safely perform maneuvers they cannot, in fact, safely perform.

It's sensible to ask if there should be different rules for bicycle and automobile traffic. But if we change the rules, it shouldn't be based one what cyclists want or don't want to do, but on analysis of the safety and efficiency for everyone involved, including pedestrians.

Sometimes you just have to suck it up and lose momentum.

Bikes can do pretty bad damage to pedestrians. Even if it isn't your fault as the car driver being involved in a crash with a biker is a pretty shitty experience. Yes, they are not as bad as cars, but it's a bad excuse.
