Why Not Build Your Own Self-Driving Car?
- KKKKkkkk1 9y agoYou know the 80/20 problem? The last 20% percent of the work require 80% of the effort? Well, with self-driving cars it's the reverse. Most start ups spend the first year getting a team of car hackers to hook up a bunch of ROS machines in the trunk to the car's controls and rigging up a bunch of sensors. And then once they're done, they have this one task left, writing the actual algorithms. And they realize that the best they can do is a car that makes laps around their parking lot (see above article), and even that takes them another year.

- afeezaziz 9y agoAfter so many startups keep reinventing the wheel, I am sure there must a template to make the wheel... Is there any tutorials on the 80% of the initial effort?
- weaksauce 9y agoThe 80/20 thing is not that... It's 80% of the outcomes are from 20% of the causes. Originally seen from 20% of the population holds 80% of the land in Italy. In software you could say 80% of the bug reports come from 20% of the bugs.
- sanjams 9y agoThere is no “right” application of the 80/20 rule. It has many applications for many contexts
- weaksauce 9y agoThere certainly is a right way to apply it. No where does that rule say the last 20 percent of reward takes 80 percent of the effort. That's grossly mischaracterizing the rule.

- weaksauce 9y agoFrom the first link: > 80% of effects come from 20% of causes and 80% of results come from 20% of effort. that's precisely what I am saying and exactly the opposite of what the gp said. the actual principle: https://en.wikipedia.org/wiki/Pareto_principle https://en.wikipedia.org/wiki/Pareto_principle
- lurr 9y ago> Well, with self-driving cars it's the reverse It's not, and that's why we won't see actually practical self driving cars for a while yet.
- IshKebab 9y agoI don't think you meant the reverse. I presume you meant it is even more extreme. The "nearly there" edge cases - the last 1% is 99% of the work.
- qbrass 9y agoThe 80/20 rule is just recursive. On the bright side, that makes the last 1% closer to 98% of the work instead of 99%.

- jerkstate 9y agoThis is pretty neat, perhaps the author should integrate with the comma.ai platform, which is open source (except for the vision part, which this post implements), has a vehicle dynamics model and hardware integration with several recent Honda and Toyota cars.
- StavrosK 9y agoYou know those five self-driving "levels"? Hands off, eyes off, attention off, mind off, or something like that? I think we need a sixth, "mind off, but this time you're driving in India". Every time I go on the road, I am reminded that what works in the US has no way of working where I live, unless the car can also automatically honk its horn and cut people off. Otherwise, in high-traffic conditions it would just stay put behind the guy who double-parked in its lane for two hours, politely never cutting anyone off.

- IshKebab 9y agoYeah you don't even need to go to that extreme. I'm yet to see a self driving car handle the extremely common situation of meeting an oncoming car on a road that is effectively single lane because of cars parked on the side. Or just, and road layout more complicated than US-style grids.
- IshKebab 9y agoThe article doesn't ask this dumb question.
- Animats 9y agoThis isn't how to do self-driving. It's how to do road-following. There's a big difference.
- frabert 9y agoBecause it will crash.
- otakucode 9y agoYou are likely to provide more of the actual things needed to make a self-driving car work than any car company is, though. No car company will give the engineers the time, resources, or control over the project to make a self-driving car that is trustworthy. But an individual might at least provide themselves a quiet environment, the tools they need, the time they need, and never be forced to rush or forge ahead with uncomfortable reservations simply because an MBA wants to meet his metric projections and knows that no court in the land would ever levy criminal charges no matter what happens.
- frabert 9y agoThe important thing is, though: will it be able to self-drive on street? No. It will be the most comfortable car there is for the maker, but it won't drive itself.
- zeep 9y agoI wonder if there's any chance for George Hotz's project to come back...
