It wouldn't surprise me if they legislate maximum acceleration in the next ten years.<p>Zero to sixty in 2.5 seconds is fun, no doubt about it, but it is fun on a racetrack. You can go on YouTube right now and find dozens of people utilising Tesla's existing "ludicrous mode" on public streets.<p>And here's the thing, if people want to endanger their own lives that's fine. But they aren't just endangering their own lives, they're also endangering both other road users and pedestrians (when they eventually lose control).<p>I don't think anything has been done about this yet because Teslas are still pretty uncommon, and the features which unlock "ludicrous mode" are even more uncommon (like 1% of 1%). But once electric vehicles are the norm and the body count racks up, we'll see legislative action.<p>As an aside you could tie maximum acceleration into road conditions, including lowing it if the road is icy or wet, or increasing it on surfaces that provide superior grip (like freeways).
