Increase road tolls, use it to incentivize companies to allow remote work.
Remote work clearly works, you just need to incentivize companies to put it in place. Otherwise, they will continue to extract those hours a day of commuting from workers, the money workers put into public transit or their cars, etc. Externalities people!
This is a matter of responsibility and perception. When you are help up in traffic you don't think of Facebook's and Google's responsibility for it, you think of the government.
The solution for this is not hard, it's just something that no one seems to have the guts for making the decision.
Sometimes I wonder, this 15,000$ incentive to employees make me think that no one is even thinking about it over there at Facebook.
So the only ones who suffer are the ones hit by a regressive toll system.
Roads have a finite capacity (you could increase vehicle speeds in order to increase capacity, but you'll run into hard limits); you properly price that capacity based on time of day. If you can't reduce demand with dynamic pricing, you will exhaust supply (in this case, congestion occurs) in short order.
