Not sure that covid is to blame.
October 2018: Austin TX. Four lane road running north-south. Two northbound lanes approaching a Y intersection. Right lane stationary as traffic waits for a light just beyond the Y. Drivers in the left lane coming to a stop adjacent to the Y, waiting for traffic on the right to move then pushing their way in.
Four years later, on the I-30 between Dallas and Fort Worth, exit coming up on the right. Cars in the far left lane crossing across three lanes, dodging between cars, to make the exit. Happened at almost every exit. Don't drivers plan ahead when they know their exit is coming?
Three days later, leaving Waco for Austin. In second of four lanes 10 mph under the speed limit. Look over my left shoulder, next two lanes are clear. Indicate lane change , look over my shoulder a second time and begin to change lanes. A car in the far left lane, again well over the speed limit, moves into the space I am about to occupy causing me to move back into my lane so fast I think the car might roll, then moves between me and the car in front, across the right lane to take an exit.
For the rest of that trip once in a lane on a metropolitan expressway I stayed there, regardless of being under the speed limit.
