There are street legal cars that use actual jet engines so I don't think there is a liability issue? IDK.Maybe Elon's not joking, but the ability to employ cold gas thrusters would come with some limitations. Clean Technica did some quick math. They calculated a fully charged 200 kWh pack could generate a possible hover duration of up to 7 minutes.

There's also questions of liability. Laterally expelling air at high velocity has some risk. Depending on the surface condition of the road, what would be a safe separation distance from other man made objects or bystanders?

The energy requirements make that pointless though. Hovering a few tons takes a lot of energy, and this gas will be stored in tanks so energy aside you will be limited on the time that thrust is available.Hmmm. I wonder. A hovercar would fit quite nicely in the tunnels of the Boring Company, where it is entirely possible to build the floors -very- smooth, and have the hovercars "hover" about an inch or so above the tunnel floor.
It would work out quite nicely in a low-speed version of a not-so-hyper hyperloop that does not bother to evacuate air from the tubes, allowing occupants to take their own hovercars and still breathe in the non-airtight vehicles (especially if they are Tesla Roadster Hovercars). Travel speeds would be considerably lower than the Hyperloop speeds that approach the speed of sound, but if its only 200 mph or so, that would still allow a reasonably short travel time for distances under 500 miles. Los Angeles to San Francisco in about 2 hours ain't too bad, y'know...

It sounds like a logical step towards a flying car.
Here is one.Link to these bad boys?
Every street legal turbine powered vehicle I've seen (like that chryslter prototype in the 60's or something)does not use thrust to propel the vehicle for the obvious reason that it's freaking HOT right behind a jet engine.
Blame ElonThat anybody interpreted they tweet as meaning hovering capability is blowing my mind.
That's basically the very first option.There needs to be an option - It won’t hover regardless of that Elon says and thinks.
The picture is a car hovering. He said "something like this". If it was going to hover, wouldn't he have said "it will do this"?Blame Elon
Here is one.

But either way, you won't be stuck behind a roadster hitting your car with blasts of air so probably a moot argument.
What is "something like" hovering? Not hovering is not like hovering.The picture is a car hovering. He said "something like this". If it was going to hover, wouldn't he have said "it will do this"?
We can flip that around. If it can hover, then why would you say it could "do something like hovering"?What is "something like" hovering? Not hovering is not like hovering.
