coro drive already sucks

It sucks because of how many people are driving on it. You can't fix traffic by adding lanes—in fact, adding lanes ends up making traffic worse because the induced demand inevitably ends up meeting chokepoints at desired destinations.

If buses didn't get stuck in traffic, they would be a much more appealing option. Instead of taking twice as long as driving as they do now, they might end up being roughly equal in time, or even faster, which is exactly how any good public transport system should be.
