There are countless videos on youtube of people recording their experience with FSD's open beta. It is probably 90% of the way there, if not more. Anyone who thinks Tesla won't get there first is peak delusional. Hate on Elon as much as you want, but Tesla are top-tier engineering.

Real funny seeing a bunch of web devs on HN talk shit about Tesla's engineers too lmao

Even if you'd be right about the 90%, I highly doubt they'll be first.

How long did it take to get to that 90% ? AFAIK they first mentioned FSD ~2016(Self-driving itself even earlier).

As the last 20% of work are often 80% of the effort we can estimate that those remaining 10 % take ~ 40% of the time. They've been at it for ~8 years , which gives an expected release of ~ 2029.

We'll see what Waymo and other competition has until then.

That 90% is about as good as a teenager taking his first practice drive with a parent (meaning an extreme road hazard).

> about as good as a teenager

a suicidal teenager

I feel like there’s some software adage about the last 10% being the hardest. It certainly holds true from my experience - even if they are 90% of the way there, it’s not a linear path to 100%.

90% done, 90% left to go.

so the 90% is really meaningless in that case.. it's what we judge to be 90% which is erroneous.

There are 90% and then there are 90% more.

A.K.A the Rule of Credibility: "The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time." - https://en.wikipedia.org/wiki/Ninety%E2%80%93ninety_rule

It's not "talk shit about Tesla's engineers", it's just a very hard problem to solve. It's easy to get it "most of the time" but extremely difficult to finish it. It's obvious it will take decades, not years to get us there. Whereas Musk insists he will solve it "this year", every year from 2014.

I live in Los Angeles, and Tesla will not get here first because Waymo has already arrived.
