A bigger, real-world problem is that cars with lane-keeping assist will steer you back towards the deer.

Some of the earlier EVs I tried had lane-keeping assist so brutal that it was like trying to steer a car with a broken power steering pump belt, if it didn't want you to change lanes - genuinely dangerous.

The Kia EV I tried a few weeks ago just felt like it was tramlining a bit when I changed lanes without indicating (no real need to indicate, on a completely empty road).
