There are some spots in the US where you drive on the left, albeit for a short distance and the road is divided. Still messes with my brain. E.g., here in the northern suburbs of Detroit (W. Big Beaver going under I-75): https://www.google.com/maps/@42.5620634,-83.1581674,18z
This is kinda like that point where Hong Kong (RHD) traffic meets mainland China traffic (LHD) IIRC. You have to do a little dance to get everyone on the same plan.
