I do. I have both vehicles. So do many cyclists also own cars. And most people may need an ambulance or may take transit .
Just cuz you personally think you don’t use something doesn’t absolve that you could still benefit from it just cuz there’s a majority who made it possible. you benefit from vehicles paying a fuel tax. You could also benefit from emergency and transit vehicles having a road to drive on if you had to ever have to be in one. That fuel moving your body is paying for the road.
