Others have already pointed out some of the obvious issues with your reasoning, but I'd like to add that improving bike and pedestrian infrastructure can actually make it easier for motorists by reducing the number of vehicles on the road and by easing congestion through traffic calming. You can actually end up with more parking spaces because while some parking spaces may be lost by adding bike paths (which is not a given!) it's entirely possible this is offset by a reduced number of cars on the road.

Also, in places with good bike infrastructure it's normal to see food delivery drivers riding bikes instead of driving cars.
