Buses have to stop to be useful. Any theoretical bus route will be circuituous for some subset of users.

The solution to these issues is to provide bus signalization, dedicated lanes, and/or queue jumping opportunities. These changes minimally inconvenience cars while significantly speeding up buses. It makes it so that a bus route, while longer, can be time-competitive with driving (or rather, closer enough that it overcomes the inconvenience of walking to/from stops and sometimes having to wait for your bus)
