Aa a practical matter, no.
Too much surface area, covered by paint.
The body would have to be isolated from all other electrical systems.
Hit you lap-top with a taser, then you will have to replace it.
Same for vehicle electronics.
If thugs learn to short the ZAP system to the vehicle cops would be in deep Doo very quickly.
To do what you are asking a Carbon Fiber body-shell could be made to work.
How much do you want your taxes to go up to pay for that?
And the vehicle still has to pass the standard crash test, EPA, etc. unless given a waiver.
As I see it the only relatively inexpensive way to do this would be an add-on kit.
Isolated elements charged by a cattle prod power supply.
But even it it was available what are the odds some looter is going to conveniently touch that particular car, after being warned by the media, their handlers, and probably a big notice on the car itself?
“Less Leathal” system would be much cheaper and easier.
An armed turret, 40 mm, for Bean Bag, Pepper Balls, tear gas, etc. could be pretty simple.
In the time it took to type this I have the basic design figured out.
Look at my screen name, this is a subject I know.
Pm if you want to start a new company. ;-)
A lot of good ideas! I can't do it but the smell of fried protester would deter others.
You can already buy an armored Suburban with a roof mounted turret. Typically they have 5.56mm gatling gun, or sometimes a 7.62 mm machine gun.
Probably hard to get for civilian use in most US cities, particularly those with Democratic mayors.
A couple of claymore mines on the roof can also be effective.
