True, but you’d probably be surprised at how often you’re actually stopped or going very slowly because of traffic when driving, especially in cities. If you compare the driving and transit times between most subway stops on Google Maps, the subway (closest thing to signal priority on a bus in most places) is almost always quicker
In a city sure, but I reckon most car drivers are in suburban / rural areas.
Fully rural driving is absolutely going to be faster than any attempt at transit can be. But most suburbs were built so people could live there and drive into the nearest city for work, so even if the driver lives in a suburban area, the longest part of their drive will almost certainly be the city bit. So I would argue for both cities and suburbs, transit can be faster than diving if done well.
