for those not from the US, I highly recommend watching the YouTube channel “Not Just Bikes” to get a better understanding of how absolutely dogshit the US is for anyone without a car.
Not only is public transit non-existent… you are nearly constantly under threat of being hit by a car as a pedestrian - as things like sidewalks, street crossing safe areas, etc. are all spotty at best… not to mention how trucks and SUVs now are bigger than ever so chances are higher than they’ve ever been before that you won’t be seen before being run over.
