Vehicle upgrade idea

N340

Have you ever been exploring in a seamoth or PRAWN suit only to be ambushed by a reaper leviathan or some other deadly creature? When you finally escape them your vehicle has lost most of its health, so you want to repair it before another creature finds you. So you exit and get out your repair tool only for the monster to come back and find you exposed. I've been in this situation multiple times recently, and this has given me an idea. What if you could build a vehicle upgrade that slowly repairs the vehicle you are piloting? Like little nanobots that will work on damage to the vehicle without the need for you to use a repair tool. If one of these upgrades exists it should be seamoth/PRAWN compatible and not too fast that a reaper attack will be fixed in a couple of minutes, maybe 10 percent health in one minute. This would save many players and their vehicles of choice from doom.
