Hmm. It sounds like your agent has an ax to grind with EVs.
Lol I don't think it's that... I think it's just more like the Insurance companies know Tesla owners are wealthier than average and now have "savings" coming from gas. So they can arbitrage them with higher rates and nobody's going to really do anything about it.
Kind of like charging solar customers more fixed costs for grid-access. Whatchu going to do about it? You're saving all this $ with your panels!
