Anyone care to refresh me on some pointers for freeway driving in an automatic? Got a drive coming up and I'd like to be "on point" as it were. It's about 100 miles, PSL varies from 75 to 60mph, basically all interstate driving. This would be in my slush box-saddled Echo. Road surfaces vary from chip-seal to fairly beat up concrete, maybe a few miles of asphalt thrown in (can't recall). The first 30-40mi are rolling hills, after which it flattens out a bit. Temps look to be ideal, high 70s so I can keep te windows rolled up fairly well. I typically run with a constant throttle setting, usually drags me down to 45ish on uphill a to 65mph on the flats. Long downhills, I can start a coast at 50ish and end up around 65-70mph. I do some modest drafting, I typically can stay about 6 car lengths behind a truck and feel I am definitely in the draft envelope. I rarely do this because of course the lack of visibility is dangerous, and if the trucks aren't speed-limited to a reasonable speed (<65mph) it's not really worth it. Few trucks seem to be limited this low. My tires are aired to 48psi. I do not have cruise control. What am I forgetting?
