Pioneer is a sucker’s bet. It’s very steep at the start and it’s too narrow for cars to pass the entire way. So you’re going really slow with cars pissed at you.
W. Liberty is no great shakes but I think you get some room during the day since it’s effectively one lane enough though it’s really wide enough for two travel lanes plus parking. Anyways, you get a decent buffer except for the section leading to Wenzell Ave.
