I'm a rebel, educated and understand that any unnecessary heat to any moving mechanical or powered on electronic component is bad. Especially when powered on and off, the heat swings are the worse. The condenser will have to work harder to keep things cool if the cooling fins can't do their job to their maximum efficiency, especially in hot climates. When I'm driving in 90+ temps for sure I'll prevent it over some bogus law to have a front plate. Cali and many other states have regulations that are pure non-sense and not argued against. Arrest, fine or tax me for not having a front plate, I know my vehicles and components will thank me. Would be happy to educate some petro-driv'n cop about the pleasure and pure performance of a 100% EV. So I take it as an opportunity to educate
If you have a few drinks and drive I then don't recommend the front plate removal since you risk being pulled over is higher for something purely non-sense.
Lastly front plates are the lowest priority for the enforcer... ever see the rear mounted hitches with the bike racks fully loaded that completely cover the rear plate. That's even worse of a "violation" since it covers your registration tags and I've not yet seen that type of profile pulled over. I have a fullsize truck with no front plate as well, winch and tow /push bumper up front, when the camper and bicycles are on there is no way if seeing that rear plate also. Had many CHP officers pass by and I've never been hassled the four years I've been all over California, Nevada, Montana, Idaho, or Utah. I also have a toolbox mounted off the front aftermarket bumper that shoots off 3-4 feet ahead of the truck. My Subaru outback and the one before it, no front plate. Ever. Its not enforced is right for Cali and the states I've driven through with no visible plates. However if you're in a police state, like New Jersey, I'd say keep the plate on.
My roadster gets driven over Highway 17 daily on my commute which has multiple CHP officers patrolling it on a regular basis, typically two cops on the road in one direction. Never hassled. A pretty roadster really is at the bottom of their list unless you have a good reason to grab their attention and tick them off.
