I moved here from London at least partially because the weather is SO MUCH better here than there. I love how much sun we get in Connecticut. Over 60% more hours of sun, on average! Over 200 days a year with at least some sun! Even compared to other American cities, we compare pretty well. In general, SAD is driven more by lack of sun than temperature, but everyone is a bit different.

I've only lived here a month, but I've yet to experience true bumper-to-bumper stuck-for-ages traffic on either 95 or 15. It gets a bit slow sometimes and occasionally stops, but nothing, nothing, nothing like traffic elsewhere. London, Portland, San Francisco, LA, etc. I've been stuck regularly where it takes you an hour to go a couple of miles (or less on bad days). Maybe it was different before the pandemic, but it's definitely not bad here.

I've just moved from London, good to see others in the same boat. I've not started the process, but have done some planning. As others have said, it looks like you need to start nearly from scratch. The only difference will be that you don't need to hold the learner's permit for 90 days, but you still need to do the theory test, the safe driving course, and the practical test. I did a bit of research on the safe driving course and was probably going to sign up for this one.

I learned to drive in the US and moved to the UK as an adult, where I had to start from scratch for the British license. I'm not sure about CT, specifically, but the tests I've had in America were far easier than in the UK. For what it's worth, as well, driving on the opposite side of the road isn't nearly as hard or scary many people think. Your brain recalibrates very fast.
