We’re testing autonomous cars in my municipal and so far they suck.
If the lines aren’t painted on the side of the road, they can’t drive.
If they meet a road sign they don’t know, they can’t drive. We have several “special” signs In Denmark, but a lot of the times it’s because the sign was too faded/dirty/covered in snow.
Of leaves, branches and some such are on the road, they can’t drive.
If traffic misbehaves, they can’t drive.
If road quality drops, or there is big pools of water on the side of the road, they can’t drive.
Basically they can’t drive.
I can’t tell you what tech we are testing, but we are trying two different manufacturers and they are both “cutting edge” and we’re testing a fleet of 16 cars over 3 years.
Another municipaly managed to get an autonomous bus going in its city center though, so it’s definitely still coming, it’s just really really far away.
Interesting insight. I wrote my concern while living in Denmark as well.
About 10 years ago, I read a paper from an Institute of Transportation in Australia about the use of low power microwave transmitters along the lanes of the highway which can "guide" the intelligent cars along the highways and also the idea of a car mesh that can communicate learning( as in I found a pot hole here that wasn't in our map, be careful!)
That sounds a very practical approach of course with the government investment on roads. After all, it is the government's charter to build public infrastructure! The car companies need to work with public policy and not try to make something within their bounds.
Yeah, well, if it's too hard to paint a line on the side of the road, imagine what would happen with maintaining arrays of low power microwave transmitters.
I think they come with different problems and can help add redundancy to data input. I would be scared to sit in a self-driving car that depends only on visibility of lines at the edge of the road. However, if there are enough data points available to the car at all points in time, then it makes the probability of failure low enough.
Imagine a system that munches visual clues + RADAR/LIDAR data + Microwave or RF transmitters embedded in the road + GPS/SATNAV + data from other cars via local mesh network. Now, that I'd think about trusting a little bit. Also, I'd definitely be watching 007 movies while my car drives me :-)
