> parking is probably private lots owned by the employer, not street parking. Picture a standard office park.

But this is still subsidized because regulations mandate that buildings have lots of parking. These regulations are typically quite extreme with requirements intended to support the 99.999% demand case (think peak hour of black friday) conditional on a parking price of $0. Most developments build the minimum amount of parking they can by law suggesting this isn't a free market outcome.

So if you want to have business you have to provide tons of parking and make up for it with higher prices for your goods and services. This subsidizes vehicle driving over other modes a transport. Especially so because giant parking lots make it harder to reach the store front by foot.
