Being around a Waymo makes me feel WAY safer than being around a human driver. If more cars were replaced, I would probably bike even more.
Seriously, Waymos follow at a respectful distance and overtake me safely. They stop at stop signs. Sometimes they even stop and wait for me to make a decision about which way I'm heading.
It's not "human driver versus waymo driver," it's "car versus no car" or "10 cars versus 2 cars" or "fast cars versus slow cars."
