Driving isn't free, but the costs you mention are all part of the cost to the person choosing to drive. That person has presumably incorporated these into their decision of whether or not to drive.
A congestion tax (or dynamic toll) is an attempt to internalize the external costs that a driver imposes on others; when I get in the car and drive, I slow everyone else on the road down, but without a toll (or an expectation of altruism toward random strangers), that won't affect my decision making at all. The goal of a toll is to make the cost of choosing to drive equal to the sum of the costs it imposes on everyone, not just the driver.
