The issues with this argument is that pedestrians, transit-users, and cyclists also pay the same sales tax. So if the goal is to have drivers take ownership over the costs they produce, we could also consider only levying the sales tax on people who arrived by car - but that's silly since there's no good way to implement that (how do you know if someone arrived in the city by private vehicle?).
The straightforward answer is to add tolls. Another solution I could see working is adding special sales taxes on parking garages in the congestion pricing zone, but then this wouldn't capture tolls on trucks, and make it harder to implement exceptions for low-income drivers or drivers with disabilities.
