Just to be clear, I do think the obvious solution to terrible things like this is vastly expanded public transit so that people don’t have to rely on cars to get everywhere, not overhyped technology and driving aids that are still only marginally better than a human driver. I just thought the article was interesting.
“Let’s invent metal boxes with wheels that follow lines one the ground automatically to get you places.”
“Oh, you mean like trains.”
“Ew, no. They’re nothing like trains, these are ‘self driving cars’. They’re fool proof!”
tesla hits someone in a dense fog because it doesn’t have lidar
Queue surprised pikachu.
Wait. Those things rely on visual sensors only?? That moronic! I mean, more so that I originally though. Please tell me that they have them, but this particular one was malfunctioning.
Musk has sai d multiple times that humans can drive with vision alone, so cars shouldn’t need LIDAR.
He ignores that humans also regularly experience optical illusions that contribute to poor driving and collisions, and that LIDAR is far less susceptible to such abberations.
Very early on, Tesla used lidar in addition to optical sensors. However, they only use optical sensors today and have for a while. Like many of the poor decisions at that company, the change to optical-only was made at Musk’s demand.
IIRC, they uses to have radar, not lidar.
Correct they’ve never used lidar. However I will say that no manufacturer has actually solved the self-driving issue yet so nobody can definitively say what is and isn’t required.
Trains are great for moving people but only from one designated area to another. With most commuters, they might be all headed to the same city but completely different parts of the city that aren’t easy to access. Their homes might all be in the same city but a 45 minute bus ride to the 40 minute train ride to the 20 minute bus ride, which isn’t helpful for what might have been a 45 minute commute by car to begin with.
Imagine if all the space between the primary radial arms of trains was filled in with street cars and pedestrian/micromobility centric spaces. Like the problem you are saying cars solve just doesn’t exist in the first place and people can still get around very easily. Even more rural folks can simply drive to the edge of this style of urban design if they need access to something. The reason bus rides are 45 minutes is because of the number of cars they have to put up with. The density of people that can be moved with shockingly good area coverage if cars are not a factor is incredible.
This sounds great but isn’t really feasible in cities that are already built unfortunately.
Unless you replace every road with train tracks, trains can’t replace cars.
LiDAR is affected greatly by dense fog btw.
