Motorcyclists generally have some compassion for cyclists in that both share trouble with cars, and both have problems with staying upright. Multiple car drivers have tried to kill me in America; no such thing happened in 10 years in Pakistan, and I've had zero direct problems from motorcycles anywhere. Collision dangers aside—there's probably stats for that somewhere, probably poorly trained, drunk, or road raging folks sitting in cars are by far the main risk—the main problem of motorcycles would be the noise and air pollution from the engines, especially when there are too many of them in too small an area, versus having somewhere you can actually walk, think, and play (these differ not) without all that horrid noise and stench. In America, this is mostly limited to a few tourist island towns where there is only an ambulance and a service truck or two, and the cyclists on vacation are all like "wow, this is so nice! I don't get the Threat Of Death™ I usually do from the American stroad".
"Stroad" is a term invented, I believe, by those crazy folks over at "Strong Towns", who probably also have things to say about congestion pricing, and why it's taken so very bloody long to implement it in a supposedly modern and advanced nation.
I favor public transit, or ideally walking (problematic) or bicycling (even more problematic). Bicycling can be very problematic in America, to the point that a tourist from Florida in downtown Seattle once remarked "wow, the cars here aren't trying to kill me!" as we sat at some stinky car-strewn intersection. Basically you're a second class citizen if you walk or bicycle. Folks in cars will yell at you or throw things sometimes, and I have the correct skin color and sex, so it's strictly worse for others.
Buses? Sure, you can find the spicy runs with all the homeless (why are there so many homeless in America? Money out the ass and yet a nation so poor …), but I've had a lot more and a lot worse direct problems with folks who sit in cars, not counting indirect problems such as the noise, air, and real estate pollution (sometimes called "the high cost of free parking"). Usually the bus crazy will do something evil like offer you a joint, or wacky conversation, and will not do something upstanding like to change into the lane that you are bicycling in, forcing you off the road.
