The congestion caused by Uber and Lyft in SF is bad. It's not because of the number of cars on the road, although that's certainly something, it's because of how those cars behave.

Ubers and Lyfts pull over at unpredictable spots (wherever the app says to) and then just throw on their flashers. It doesn't matter if they're blocking a lane in rush hour they just stop.

I will never for my life understand why an Uber or Lyft driver thinks it's any better to double park in an active lane of traffic than to temporarily pull out and block a driveway or a red zone. Both are illegal, but at least one of those doesn't block traffic and endanger other drivers/bikers.

Almost every day I see an Uber driver double-parked within 50' of somewhere they could have pulled over safely.

If the cops would give out a few more tickets for this, the behavior would get better and so would the traffic. And then we wouldn't have to tax the road use. Taxing the road use is crap, everyone should be able to drive their vehicle on public roads as much as they want as long as they follow traffic laws.
