Buses aren't horrible.

• they feel safer in terms of crime, which might not be an issue you deal with but for over half the population it matters
• they can often go around problems. One bus on the same line up ahead has an issue that has no real impact on the bus you are on
• lot easier for the disabled to go on and off compared to down into a subway
• you have a small degree of privacy
• Mechanical problems? Get off the bus. No biggy.

I do understand, I was a subway guy for the longest time, my wife would take the bus every day and she converted me.
