Do you not touch the brakes or engine? Those are far more safety-critical.

  I'd only really call the brakes there safety-critical but either way they're at the base layer pretty simple hydraulic systems that are very well understood (and there's always the e-brake which doesn't usually get screwed with). Even that doesn't get around the fact that these systems even in their full factory installed working order have driven directly into the sides of semi trucks, lane dividers and into the back of completely stationary vehicles.

    Look at the Toyota unintended acceleration incident to see how dangerous a malfunctioning engine can be. (Even if it ended up just being floor mats or driver error, it shows what can happen in that case.) Other cars in full working order drive into stationary vehicles and lane dividers every day. Nobody’s freaking out about DIY mods for those.
