Injuring people, bricking after going through a carwash. Multiple off-road embarrassments—the Cybertruck has had a tough first 12 months. And right here we’re once more exhibiting you one other instance of why the Cybertruck is doubtlessly harmful to drive.
At the moment’s newest Cybertruck failure involves us by means of a tweet on X. Within the six second video, it exhibits a Cybertruck with a driver behind the wheel rapidly turning the wheel left and proper whereas the entrance wheels are in view. It doesn’t take a eager eyed observer to note the lag between the time it takes for the driving force to show the wheel and the truck’s wheels to react.
Now to be honest, all steer by wire programs lag. It’s only a results of having no bodily mechanical connection between the steering wheel and the entrance wheels. As an example, Engineering Explained did a deep dive on the Lexus RZ’s steer by wire yoke system. They known as it higher than Tesla’s but it surely nonetheless had issues. One among which was the lag. From their commentary, the RZ had a 0.28 second lag when sitting in a single place.
The Cybertruk seems to be to be worse. Apparently this steering lag has been talked about on-line now for months. In a thread on Hacker News discussing one other Cybertruck steering lag video on X from earlier this 12 months, a person requested if this might be a problem. The video is 20 seconds lengthy, it runs at low velocity to raised illustrate the lag. The user observed and calculated based mostly off the video that lag seen was 125 ms. That’s sluggish. For context, if I used to be on-line gaming in a match, that’s match ending lag.
Whereas it’s true that steer-by-wire programs have a quicker steering ratio for decrease speeds and a slower one for larger speeds, this type of lag might be harmful in a scenario the place a correction is required as another user on Hacker Information identified.
⅛ of a second is extremely sluggish. Delays like that fuck up your notion/suggestions loop. In the event you placed on headphones, and hearken to your personal speech delayed by that period of time, ,you’ll be able to hardly converse (delayed auditory suggestions). If it’s a must to management a tool that delays that a lot, you’re susceptible to overreacting, after which getting into a run-away correction cycle, which isn’t good in a heavy, fast-paced machine.
Hopefully we don’t find yourself seeing any movies anytime quickly the place some Cybertruck proprietor came upon the onerous manner simply how dangerous this lag can get.
