That’s because the vast majority of people would still use the roads. Let’s say I live in Saint Albans, I don’t but I think it’s a good example. It’s about 35 minutes from Saint Albans to the airport, it’s a similar amount of time to most of Burlington and South Burlington. If I hop in my car 40 to 45 minutes before I start work I’ll generally be fine. Now if I’m commuting by rail I have to get to the rail station whenever there’s a train that will get me to work on time and it’s unlikely for most people but that time will be convenient. I will then need to transfer onto a bus or more likely more than one bus to get where I’m going. So not only am I at the mercy of whenever the train is running I have to assume that the buses will be on time plus I will still have to walk since my job being on the bus route is no guarantee. Then all of this Hass to be done in reverse and again the buses and trains will likely not sync up with a lot of peoples start and end times. I don’t know about you but the last thing I want to do when I’m done working is spend an hour or two trying to get home when I could’ve done so in 35 minutes. I’m tired, my feet are tired and having to walk to a bus stop then stand outside in the cold hoping the bus comes by is not something I want to do.
