Fast land vehicle is not a glitch, but an exploitation of the physics engine. Since everything is a flat block with no rough edges, and things only go a certain distance from others when they are falling on to them (hence the advent of welding), you are able to go inside a series of blocks not welded to the ground and push on it if it's light enough.

Since multiple connected blocks are not treated as a single object but rather a series of blocks, when you push on the window the other blocks will go too, as welding is stronger than movement. This is due to a lack of friction, as the only thing in roblox that stops the moving of an object is another object of the exact same speed, anchoring through a script, manually pulling back on a vehicle, or, most commonly, the weight of the object pushing it down.

Since the fast land vehicle is a small, light, object, and the physics engine doesn't give a crap about connections or friction, the fast land vehicle is  not a glitch, and simply a masterpiece of robloxian engineering.

Although it was probably invented by a person who didn't know roblox studio existed.

I got this information because I took a player-made course in robloxian physics and non-scripted devices.
