Title saids it all: I suggest that beam could starts to create a framework of electric base/multi-motor powered vehicals, which means that a system that allows motor required no air to run, but use up charged battery power as fuels also generate alot of heat(which in real life electric car usually do), that could greatly expand how the game can be mod with, and alot more immersive rather then using jets as power sources. Hybird cars, which would be like normal car, but with a small back-up power source that drains less fuel when the secondry motor kicked in, or with a different transmission that can be gripping the road more AWD then AWD, and cut most the turbo lags when hybird cars have turbo(s). Electric system and waterproof/water resistence after engine bay damaged, The current game did not reflect how electric systems work on real cars, usually the car would be total lost and the lights would be fine and able to light up after gone under water and back, that should never happened. I suggest that the game could add a box in the engine bay that can be damage and leak if go under water after it breaks the seal, battery could start causing shorts in the electric system and damage parts like ECU and spark plugs, and randomly disable/enable all the lights inside or outside the car. Also about electric, I suggest that engine parts could have a sets of ECUs, generatiors, fuseboxs, and batteries to choose with, those could be fine tune the car's power/survivablilty(after lost/bend the hood and have all the harsh envirement covering them, parts use electric would face risk of shortage) without insert turbos on them (which I really hates turbo lags.....) Floatations addons, there are serveal cars(which have their counterpart in game, like D series pickup truck, and heavytruck) in real world have floatation tanks to float over water, why not make them ingame? Tread system, I don't know is this a easy or hard to do system, but how about create tank treads system ingame? There are halftracks exist on the world and still be used massively, so please?
