https://www.bbc.co.uk/news/uk-england-northamptonshire-51510531 I've never had a problem riding a bike in Europe. I just keep my throttle hand near the pavement. When I've hired left-hand drive cars in Europe then I've found it quite easy to drive on the right. But driving a RHD car on the right is a bigger challenge. Do US service people get to bring their cars here, or are they driving LHD cars on the right? If they are then that is inexcusable.
