You won't know that without orientation, though, if they are stopped.
By definition if they are stopped, they don't have a direction. And from a stopped position car can move forward, backwards and somewhat sideways.
In theory.
In practice, the orientation of stopped cars in traffic is used very effectively by everyone of us on a daily basis, we don't even think about it probably. If a car is stopped, facing traffic in an intersection, it is probably waiting to merge or cross - and we keep an eye on that. If it is facing the other way around, it is probably waiting to park or drive away etc., we hardly expect them to back into the traffic... could happen, but the probabilities of it can help autonomous vehicles make similar judgement calls.
Also one can estimate potential turning arcs based on the angle of a stopped car, no matter which direction it takes. Knowing the orientation of a car makes a massive difference in this, compared to simply knowing a car is there.
Look, I'm the first to admit Tesla's more aggressive approach to self-driving development can certainly yield consumer-facing results faster than the competition. And in some areas, auto-steering especially, it has. But IMO that is separate from analyzing their vision prowess. Who has the best vision and who does what with their vision are two separate questions. What this thread IMO is mostly about is the vision part, since that is what your super-great findings provide us "vision" into.
Using that vision to do stuff is separate: AP1 is actually a good example of this. A lot of companies use MobilEye's vision chips, but only Tesla used EyeQ3 so aggressively with AP1. Had Tesla put a fisheye camera as a second camera (EyeQ3 supports several cameras), they could have done Autosteer+ with it, done steep hills with it (without the narrow camera losing sight of the road), and still have traffic-sign recognition and all that, years ago. Then again, other companies with very small and conservative ADAS teams used the same chip(s) much less effectively even in the AP1 era and are only now beginning to reach those AP1 levels in consumer products...
IMO there is little reason to doubt MobilEye's vision surpasses that of Tesla's - and I must admit I'm surprised you seem to think so and didn't see how obviously the narrow AP1 camera issue being the reason it can't see hills or tight curves. Personally, I find it likely EyeQ3 is already superior to current AP2+ in vision with similar cameras and even more likely that EyeQ4 is significantly ahead...
@Bladerskb does have a point: MobilEye sells these as chips to OEMs to use, they must be finished products. MobilEye also has a very long and public academic history of research and showing their results in those settings. IMO there is little reason to doubt MobilEye's vision capability.
The interesting question here IMO isn't who is leading vision (that would probably be a debate between Waymo and MobilEye), it is how quickly can MobilEye's (or Waymo's, if they so choose) partners use that vision ability and create effective results the consumer can buy and use. That is IMO Tesla's real edge (and a bit similarly Comma.AI's edge) - they obviously are far more willing to run with more uncertain results and ship that to consumers. As a consumer, getting faster results with Tesla seems definitely possible. Here is where, say, I and
@Bladerskb differ: I am definitely excited about the potential of this and do acknowledge a meaningful difference in approaches. I look forward to AP2 V9 (even though I'm apprehensive about the UI changes
based on past experiences).
Other car-makers are much more conservative in their approach. Then again, others are more willing to use additional sensor technologies to help make their progress in other ways, including lidar and radar, which could also make some difference. I also find it possbile Tesla will be left behind in actual Level 3-4 progress (driver not responsible), while offering similar or better progress on Level 2, where driver still remains responsible for example... which would give the competition another kind of edge, of course. We shall see how it all plays out... Interesting times.
Thank you
@verygreen and
@DamianXVI for the good work in bringing us a glimpse of what Tesla's vision status has been recently!
Keep up the good work!
