Those of us that grew up in MD not far from 301 think it's terrible now. It used to be a fairly straight shot through Waldorf with 1 traffic light at Rt 5, now it's light after light after light. One more location that traffic outpaced the roads. South of Annapolis til you get to VA at the Nice bridge is stop and go, with many traffic lights. I've driven it over the last 30 years. Less trucks driving fast than on I-95, but that's about it.
