Just out of curiosity, what if a road had concave shaped lanes such that the steering was always biased toward the center of the lane. Then at some point the surface changes. Would that have a similar effect of causing drivers to potentially crash at that point?
If not, then any driver assisted implementation should emulate the feel of a concave road (or road ruts) as much as possible. Make it so that the car is more comfortable to drive, but just subtle enough so that the driver's attention doesn't drift too much.
One of the demos showed the car "staying level" as it swerved aggressively. I wonder -- might it be reasonable to have it overcompensate? If a car could "lean into" a curve like a motorbike, it could help driver comfort by turning some horizontal acceleration into (passenger-pose relative) vertical acceleration.
I'm not sure the ability to drive is that much worse -- for constant curvature surfaces it should just increase traction. I guess the suction could be regulated if a certain varying inclide causes trouble.
We don’t know the perspective or the contours of the illustrated road well enough to say this. I could imagine some perspectives where this actually works out, especially if the tires are causing the vehicle to slide sideways.
Only if you want to look like a drunk driver. I wish it worked like that, but all it does is jerk back to the center of the lane about half the time and then complain that "steering is required".
So long as you are happy giving up 1/2 of your traction, that would only solve corners if the steering wheel is moving. Say your right wheel hits a bump. Even with zero steering input that right wheel is traveling slightly further than the left wheel. (Up and over the bump is longer than the strait line driven by the left wheel.) There also also times when the steering wheel moves but the car remains strait (crosswinds). The further one looks down this rabbit hole, the more appealing a simple mechanical differential becomes.
Not my car but a member of my family's car does that with the steering wheel and I hate driving it. Granted I live in the country, but I want to be able to go over the line slightly to avoid something in the road without it trying to shove me back
That doesn't necessarily account for people getting car sick on long, smooth, winding canyon roads driven at constant speed. The jerk induced by following the curves in the road should be lower than that caused by braking.
Funny enough I feel like only older “less realistic” driving games would let this be an advantage, Forza for instance realllly slows you down from the friction of hugging a wall
Yea, I get it for driving on track, but not on the highway just managing space between you and the car in front.
Re: your curvy road, I would say at that point you might just be driving too fast for the load in your vehicle. When passengers are onboard, a smooth ride will beat everything 99% of the time. If I have to suddenly break for a sharp corner, then I apologize and slow down so it doesn't happen again.
It's a very natural thing to unwind a wheel with a dragged hand when entering traffic from a stop on a perpendicular side street. And I'd argue that's far more than 5% of the substantialsteering a driver does.
They could have just flattened the circle on the top like a D wheel to give some clearance on the instrumentation. Interrupting the continuous shape with a yoke is the problem, not that it isn't a circle.
It's as if the decision makers behind the yoke don't drive themselves, or were actively trying to make the driving experience worse to compel FSD adoption
