Driving is cheaper than flying when carpooling (again, you're not from California so you don't know about airline commuter sales and prices where you can fly from Norcal to Socal for $100 or so). But when you factor in the actual costs of driving: maintenance on your car and the tax dollars, bonds, and compounded interests and costs paid to build and maintain said freeways- is it really cheaper?

And airports are very expensive to maintain but people use airplanes all the time. Amtrak is also popular (and doesn't turn a profit). HSR would be another form of transportation alongside all of these highly subsidized and expensive modes of transportation- with freeways being the most expensive, hands down.

And hopefully hyperloop as well
