In general, driving a motor vehicle in America is a widely varied skill. Every state has its own laws and guidelines on how to handle their cars. For example, in New York, never use your tum signal when you want to change lanes. New York City drivers respond to this by crowding the lane you are trying to get into. Only use your tum signal for turns. M)((Meanwhile), one peculiar thing the drivers in Pittsburgh like to do is not to go right after the traffic signal turns green when there is a car waiting to make a left tum at the opposite side of the crossing. It seems the local etiquette is for the first vehicle waiting to turn left to have the right of way, then traffic may resume at its usual wild pace. It can be quite embarrassing not to know this rule as the first or second vehicle in line at the intersection.
Can you replace "meanwhile" with "on the other hand"? Do they have the same meaning?
