No need to bring race into this - people into calling out car culture want to build and upgrade cities to make things better for everybody wherever they live. Bikes are obviously a lot cheaper than cars too, so better bike infrastructure everywhere reduces inequality in a way.

Anyway, as to your other points - firstly, changing or building cities in a way that is not car centric doesn't mean there are no cars and nobody drives - obviously people still have to and will. Actually, building cities in a way that is not car-centric is safer for people who still drive, and there's a lot less traffic, so that's good. It's just even better for people who don't or can't drive (think of people under 16 years old, who have little independence to travel living in suburbs).

It should be noted too that non car-centric cities are much better for e.g. elderly people to live in, because everything is much closer, and good cycle and walking paths are much better to ride mobility scooters on. Things being in walkable distance also helps people age better, because the exercise means you retain your mobility longer. It's pretty scary how as people age, you get to a point where if you're not staying active, you really quickly start to lose the ability to be active, which is a unfortunate spiral.

The last thing - it's not just bikes (look up the YouTube channel with the same name, by the way - it's awesome). Improving zoning laws and building good public transport is also a key part of the puzzle, and helps solve lot of the issues as well.
