Hate to tear back the curtain a bit but uh, as someone in the industry who specifically is involved in commercial vehicles? Not something we ask at our endThey don't give HUGE discounts on car insurance to people with A licenses for nothing.
Mind every insurer has its own things and, just, your average commercial vehicle fleet is going to be large enough you're not going to be asking driver to driver questions. A semi's probably cheaper than what you'd expect on the policy,
I would argue it would help with onboarding new people though. You've been playing D&D for ages, you're already well into it, but new people come. 5E's good at the onboarding process but imagine something like the nightmare of character building that is 3.5E instead. If you had ways from other gamers to explain that to newcomers, it could help them get in. Heck, even folks raised on one edition of D&D who ignore others.And that means nothing, because I've played with multiple great DMs who haven't. I'm not the one claiming objective fact to subjective things. You are. You can't point to a single technique or rule from any game that will objectively improve D&D. You simply can't do it, because no such rule or technique exists. Every last one of them is subjective. As is, by the way, DM greatness. Mercer is good, but I wouldn't call him great. I've played with better(again subjective opinion as this all is.)
I just got to watch this exact scenario play out with a friend. She has never done any sort of TTRPG, but due to a failed attempt to get a D&D session off the ground, at least has a vague knowledge therein of 5E stuff. She's in a World of Warcraft guild, and despite being an MMO, WoW has a pseudo TTRPG scene going on, not really using a system so much as just a vague "Roll d20, highest wins" type of deal. Your average bones.
Her World of Warcraft guild decides to try and set up a thing using a modified one based on the 2d20 system. So, y'know, you've just set up a roll under system on someone who is so completely outside the TTRPG sphere she has genuinely never heard of 'roll under' being a way to do things. This GM does not explain this in a way that is helpful for what is basically a new player. I, as someone who's at least got experience with all of this, manage to help her through it, but the GM not really helping things has pretty much turned her off any roll under system for life, simply because it was explained poorly.
(i could though point to many technique or rules from any game to improve. Certain editions of D&D, though. Most of these come down to 'why are grapple rules', mind.)
