It's not just public speed limits that will keep the Lucid Air below 235MPH. As with Tesla, Lucid is unlikely to lift that 155MPH software speed limit on production cars lest it anger rival luxury brands who've informally agreed to that restriction in the name of safety. You certainly wouldn't get this kind of breakneck pace from the base-model Lucid Air -- you'd need to pony up for a high-powered variant to achieve this feat even if there were no restrictions. Also, notice how this prototype is both stripped down and includes both a roll cage and a large spoiler? It's going to have a much easier time hitting 235MPH than a production car loaded with creature comforts and no real racing amenities, especially when it's driving on a road instead of the track.

As such, this is more of a theoretical exercise than a representation of what you'll actually get. With that said, it's still useful as a demonstration of how far EVs have come from the days when they were barely quick enough to keep up with traffic.
