yeah that was why I added the "probably". Like as I was writing it I was already questioning it, like an electric police car should be more expensive initially... right?
turns out most police get special deals through a "cooperative purchase program" essentially all the districts buy in bulk and the price goes way down, the heavily upgraded police versions wind up often cheaper than you'd pay as a consumer for the standard version. So the fact that it's an electric police car doesn't make it more expensive, but the fact that it's basically a one-off cop car does. But you're right, a one-off interceptor SUV is more than a high-end Tesla model S, and more than 3x the cost of a Model 3.
also electric is alot lower maintenance. But actually the biggest cost on a police car if you add up fuel mileage and repairs and initial cost etc etc is depreciation. pretty much true for any equipment. but it's also a kinda shitty metric cuz they're not selling the sed cars at final "fair values" but depreciations still a tool if you're comparing cot of ownership and it's unsurprisingly the biggest factor. and for electrics, it's way higher. (in large part because of tax incentives that ONLY incentivize buying NEW electric vehicles...)
TLDR: a lotta bullshit exists around electric cars, police cars, taxes and depreciation, but assuming that an electric police car is automatically a waste of tax dollars shows a lack of understanding and appears to come more from unfounded bias against "progressive" changes (which include e-vehicles) than from sound arguments on a cost basis.
