I ran across a similar twit a couple of years ago on BC#3. The road is a twisty 2 lanemountain road, with passing lanes every 15 miles or so, a cliff on one side and a rock wall on the other. Going through the twisty bits, this guy would drop to 30-40 mph. Then on the long uphill passing lane sections, he’d speed up to 60-70 ish.
I was driving a little 2.9 litre v-6 “powered” pickup that was loaded, so I couldn’t get past him on the 10% of the road that was safe for passing. I eventually got angry enough with him that I passed him using the shoulder in a hairpin corner, leaning on the horn the whole way.
(I was in a bit of a hurry, since my dad had called me for help, mom was in hospital, and I was 6 hours away when the call came. They’re both fine now, btw.)
A hint for my fellow drivers: if you’re not comfortable at the speed limit on a section of road, driving slower than said limit is fine, just STAY at that speed once a passing area comes up so others can get by you!
What happens a lot is that they don’t pay attention most of the time, but when someone starts to pass they snap out of it, check their speed, and start going a more reasonable speed if they have been doodling along. Meanwhile the passing car has to speed in order to now pass them. Of course sometimes I think it is just maliciousness. The worst is someone in the passing lane who does this, but for cars passing on the right.
