I know people might flame and say "DON'T SUGGEST VEHICLES, ITS ALREADY BEEN SUGGESTED A BILLION TIMES" or something similar, but I just came up with a creative way to make vehicles.
Since we start with 50 blocks, why not make it so you have to build your vehicle? For example, if you wanted to build a car, there would be a certain way u have to build, preferably in a shape of a car, and once that shape has been completed, it would turn into a blocky type of car, ofcourse smaller than the block otherwise whod want to drive around a huge truck sized car.
Maybe also a helicopter or something, build a heli, it turns into a heli, but then again, heli physics and controls would need to be created.
This is just my suggest IF vehicles were to be considered being added, then this might be a good way to obtain them :P
Idk it still has many flaws such as, people might spam build choppers or something, or if youre building defenses and it somehow ends up being in a shape of a car then you wouldnt want it to turn into a car, but then again im only suggesting :P
