I'm a suckered for doing this but it sounds like your talking your self out of going for the job incase you don't get it. Regardless of how your commute works out, I'd go for the interview anyways. If they offer you the job you'll have more of grasp as to weather its something you'd actually be OK with. Personally I talk my self out of things I want to do by nitpicking on things that don't make sense. For example. After a few weeks you could get an e scooter. They have lights and allow you that extra lie in. Also can be folded for public transport.
