An accurate analogy, although a better HN automobile analogy in the sense of more accessible to the general public would be trying to drive SUVs like cars results in rollover accidents.
Its an error of regulation to permit a ridiculously safety critical real world physical system to digitally emulate a historical virtual system to save training money. Its a perfectly good aircraft on its own; it just has intentionally hacked and modified controllers to fake being another plane, and those hacked and modified controls unfortunately kill hundreds of people.
Given the merger of government and aerospace its going to be a huge dysfunctional fight where neither side can back down and admit they need to change things. My guess is for purely political reasons both sides will admit guilt, although its obviously completely a government failure. On the other hand, as per the recent VW Diesel situation, if the government implements stupid regulations that are followed to the letter resulting in predictably dumb outcomes, the government accepted no blame and the company was attacked. There are strong indications going both directions which will make this interesting to watch.

That analogy implies that the pilots were trying to fly the plane in a way that it couldn't handle. A better analogy would be a safety mechanism on the SUV that prevents drivers from turning too sharply and rolling over. The crashes are caused by that system incorrectly measuring the turn rate, forcing the car to drive straight, and have it run off the road. Really, there's nothing wrong with the MCAS system in theory. Plenty of planes require computer controlled inputs to fly safely. The problem is in the execution. The base model lacks redundancy and pilots weren't trained well enough to handle the system malfunctioning. And in the case of the Lion Air crash a poor safety culture. Honestly, the problem is probably already solved at this point. Correcting the issue that caused the crashes is simply flipping a switch. The issue is identifying what's causing the control issues to know which switch to flip. Every pilot should be hyper aware of the potential issue and they'll be able to easily diagnose and fix in flight issues.
