That can certainly be an issue around here, but it was interesting when Colorado legalized pot. Then the Subarus were suddenly going unusually fast in the AM - only to slow to a crawl after having visited a dispensary.
Here it is Subaru and Wrangler. I will damn near drive a family off the road, to get in front of any Jeep Wrangler, the single worst on-road vehicle ever built.
When people would haggle the best price I could give them I would start to raise my price.
Never really needing the money for any implement or item I'm selling, I usually just tell the seller to offer me whatever they think it's worth. Roughly 10 times out of 10, they offer more than I would've asked for, to begin with. When faced with the opportunity, most good people are too embarrassed to lowball someone, in my experience.
A relative was an EMT on the local air ambulance. He says that his biggest customers were bikers. Second biggest was Jeep drivers.
I would have put ATV'ers/snowmobile riders (especially inexperienced ones on rental units) pretty high on that list. Seems hardly a week goes by without an accident or three with them with excessive speed and/or unfamiliarity with the trails/equipment a major contributing factor.
My MIL worked as an ER nurse in the great lakes snow belt. She saw at least one snowmobiler almost fully-decapitated by livestock fencing. I had a buddy hit a deer at high speed on another.
