The cost of vehicle ownership is a sizable toll people already pay. Even a beater is $300/mo. for insurance and maintenance, not counting the fuel. We've dumped our second car (2010) to shed about $900/mo. in insurance, maintenance and loan payments.

And then you've got this double-edged sword that Lyft is cheap enough to be competitive with vehicle ownership + parking (for commutes up to about 8 miles), and the Rideshare cars have automatic free access to the HOV lanes. So those people get to ride fast without removing a car from the road as the HOV program intends.
