The US’s record of reliable and efficient public transit is abysmal. Out west here you’re lucky to even catch a bus that takes an hour and fifteen minutes to get you where a 15 minute car ride would.
Dont have a lot of experience with US, but Seattle and Redmond (which are on the west coast) had pretty awesome public transport.. I was able to navigate it pretty easily even though it was my first time in US, and it went pretty much everywhere
Go an hour south in your state (or over to the eastern half) and you'll see what GP means.
