I love how clever this is!

If I wasn’t pretty sure that gunning the engine in park repeatedly is a bad idea (and would draw more than a few stares when done from a street-parking space in Manhattan) I’d give it a try.

Would very much like to see a video of someone using this.

Here is the video from the creator I think: https://www.vice.com/en/article/jpn45k/watch-this-dude-play-...

Here’s the link to the actual video: https://youtu.be/zOSN66wYbTE

The input lag looks terrible.

[ilyt]

My guess it is using some periodic signal one of devices on bus sends instead of querying it directly, code looks like it only process signals, not sends any queries

[Waterluvian]

I’m also of the impression that dry turning the wheel isn’t great for the tie rods. But I welcome a car person to teach me the truth.

[sokoloff]

Park the car with the front tires on two pieces of cardboard (each) to limit the turning forces.

I wouldn’t sweat it for the duration of demo or until you (quickly) got bored with it. You do the same everyday you parallel park a car.

[grepfru_it]

Dry steering will also damage your concrete or pavement. Should probably jack your car up while doing this or turn up the sensitivity so very small inputs translate to larger turns

[frosted-flakes]

It will damage your tires more than the concrete.

[kube-system]

Concrete, yes. On the other hand, a hot residential asphalt driveway can be boogered up pretty easily.

[ilyt]

Or just on jack stands

[DANmode]

Worry about your tyres.

[grecy]

The amount of force you're putting into the system, regardless of if the engine is running (and therefore the power steering pump is pumping) or not, is a fraction of the forces the system handles constantly while going around a corner at 60 mph or hitting a pot hole.

It's perfectly fine.

[short_throw]

For steering you're exactly wrong. Drive an old car without power steering, on the highway you'll barely notice, but you'll be using all your might to park. It's much easier to steer a rolling tire.

Power steering systems create heat and rely on airflow for cooling...so prolonged steering back and forth in a parking space is a worst case scenario for the system.

> For steering you're exactly wrong. Drive an old car without power steering, on the highway you'll barely notice, but you'll be using all your might to park. It's much easier to steer a rolling tire.

So you're talking about the force the human has to use to turn the steering wheel. In a car with power steering, the human doesn't have to do much, because the pump effectively amplifies the force and exerts it on the tie rods, steering, etc. etc.

Either way, the forces on the steering components are the same, and they're not a problem.

> Power steering systems create heat and rely on airflow for cooling...so prolonged steering back and forth in a parking space is a worst case scenario for the system.

I assume you mean while the engine is idling.. in which case the main cooling fan will kick on when the temp of any component requires it, so it's perfectly fine.

[blowski]

I'm no expert, but what you're saying goes against everything I've ever heard, including from a driving instructor and senior engineer at Ford. The internet also seems to disagree with you.

[barbazoo]

Doesn't matter if the engine is running. It only matters whether you're in motion or not. The engine running just enables power steering but the strain on the steering system and the tires are the same.

[Waterluvian]

Thanks! I’ll chill out about avoiding it then. What you say makes complete sense.

[jamiek88]

Won’t damage tie rods or anything mechanical. May shorten life of tyres.

[ilyt]

I... don't think you ever driven anything without power steering.

[sokoloff]

Surely, you’d do this key on-engine off. (Key on so the CAN bus is active; engine off for obvious reasons.)

[deepspace]

Or you could play while driving. Solves the accelerator and steering problems at the same time.

[lukasb]

This would be a LOT of fun on salt flats

[ilyt]

Extra challenge, drive the same track in real life and in video game

[sokoloff]

Extra-extra challenge: drive a different track in real life as in the game.

[ilyt]

Reminds me of some speedruns where 2 or 3 games were played at same time via one input

[sokoloff]

Have you tried https://flappybirdle.com/

[tylergetsay]

No power steering if engine is off, would be hard to play

[Gordonjcp]

I don't think you'd need to have the engine running for the throttle pot to send data.
