I've had multiple professional-managerial friends tell me they personally won't bike because that's something they left behind in their childhood or broke-student days. It's beneath them now. But you're right, people also complain about bike infrastructure projects taking space from working-class drivers to benefit white yuppies.

We see this often with urbanist topics. New multifamily construction is gentrification and colonization if you lean left, full of crime and a threat to our schools if you lean right. The only widespread agreement is that it represents the Other. The stranglehold of postwar suburban car culture on the American psyche is self-reinforcing at this point.
