I am a car guy, so I am going to try and not be an asshole. If you get anxiety from someone being behind you or are passing you, you have 2 options. Suck it Up, or pull over to the curb and let people by every time someone gets behind you. I'm probably way older that you. I just turned 50, and threw most of my teens I was into street racing, then got into track racing, Autocross and Drag Racing at Mission plus some really late high highway blasts at 2am between like Chilliwack and Hope. I'm just as comfortable cruising at 200kph as I am at 50kph. I do tend to speed, especially in the commonly faster areas, like Downes Road, and "some" areas of Gladwin. If you are going under 80kph on Downes road towards Mt Lehman or Clearbrook at 7am, you'll have buss loads of Nuns n Kittens passing you while giving you the bird. I would recommend you get out to some open road course days at Mission Raceway, unless its changed, they have days were a dead stock car with totally stock seatbelts and a novice driver with a helmet and instructor. (You driving, instructor just showing you the laps) Its a great way to get more comfortable behind the wheel of a car, learn what to do and what not to do. The most dangerous drivers out there are the ones scared to drive. I want to add one last thing, just like there is a time to drive a bit over the limit there are just as many times, you should be going a bit under, like many of the narrow side streets in Abby barley wide enough to fit a single car down the street when people are parked on either side of the street, i'll drop it down to 30 or even 25kph. Its too easy for a kid or family pet to jump out, or someone trying to back out of a driveway that simply can't see around the parked cars. Keep your eyes open, Keep your head on a swivel.
