Reminds me of a situation not long ago.

I’m in left lane on highway. Tesla ahead of me but quite a ways away.

I realize as I’m driving that the Tesla is moving quite slow for the left lane driving. And before you say it, yes there are lots of people speeding in highway left lanes too.

So - I passed on the right rather than tailgate. Look over and see a guy leaning back in his seat. No hands on wheel. Could’ve been asleep. And driving 10-15 mph slower than you’d expect in that lane.

To your point about using it FSD the way you do, makes total sense to me. Which implies you would also cruise at the right speed depending on the lane you are in, unlike my example.

One of my major complaints about FSD is the 'speed profiles'. You used to be able to set a target speed directly. Now, you can only select a profile. You're either going the exact speed limit, 2-3mph over, or essentially 'with the flow of traffic' which can lead to speeding +15 over the limit.

Didn't know about that feature. Thanks for the illumination. On verge of going full electric and looking at BMW, Lucid, Porsche, Rivian, Tesla.

I wonder what's taught to new drivers about this sort of situation. My intuitive feeling (driving for almost 30 years) is you drive with the flow of traffic when traffic is present. I don't see too many left lane drivers glued to speed limits, but it's obvious when someone is a fast or slow.

It's worth noting that older Tesla's pre-2024, are stuck on an old version of FSD due to compute limitations. Recent FSD, generally, does not hang out in the left lane and is very good at recognizing when vehicles approach from the rear. It will move to the right lane to allow them to pass.

Excellent -- noted.

> the Tesla is moving quite slow for the left lane driving. And before you say it, yes there are lots of people speeding in highway left lanes too.

Is that code for "the Tesla was following the law by driving within the speed limit and I don't find that acceptable" or what?

> I passed on the right rather than tailgate.

... right, since those are the only two options. Tailgating is just one of the potential valid options to choose from after all.

> And driving 10-15 mph slower than you’d expect in that lane.

So not "slower than the speed limit", but rather "slower than you'd expect". Sigh.

I won't comment on whether it's acceptable to speed or not. I don't think that's the point.

Most highways I drive on exhibit a predictable pattern. Slower folks in right lane. Faster folks in left lane. Maybe those slower folks are at the speed limit, or above, or below. Left lane folks somewhat faster.

Should everyone obey the speed limit? Sure! Hard to argue that point.

My observation was a Tesla driving at - let's call it "right lane speed" in the left lane. Maybe slower. Slow enough that you'd soon see a predictable back-up behind the car - some tailgating, brake usage, etc. The stuff that in my view leads to more accidents, swerving, and phantom traffic that occurs when people pile on each other, use brakes excessively, and end up slowing to a crawl.

FWIW: The "is speeding acceptable" question is somewhat resolved by police. I rarely see people pulled over for speeding within the flow of traffic, vs. somewhat swerving in/out or just driving much faster than everyone.

Don't remember the last time I saw an officer pick a car out of a normally flowing left lane to issue just that one driver a ticket.
