The Nikola is presumably the only electric vehicle in the game, as it is the only vehicle besides the Bicycle that does not hold fuel.
The Nikola gets its name from Nikola Tesla, a pioneer in electrical engineering.
This could also be a reference to the Tesla car brand.
The Nikola appears to be based on the real-life Tesla Model 3.
The Nikola had a bug that causes the battery not to drain. This has since been fixed and it will casually refill the battery while it is parked somewhere.
There is currently a bug where the Player is able to obtain unlimited batteries by stealing the battery out of the car. It will then start to make a new one and charge it back to 100%, even if there is NO battery in the car. Also, this means that headlights will last forever since the battery charges faster than the headlights drain the battery.
