That's a car not a tram
Mini bus, not a car
It's a cram.
It runs on rails, which is called a tram or streetcar
I don't see any rails in the image?
Top left, the rest are magnetic rails under the red line
If it's not steel on steel it's not a tram.
Ok that's awesome. I didn't know something like that existed.
So, the tram has tyres? Like a bus?
Or is it maglev, which would be nice?
It probably just uses the magnetic "rail" to guide it on the road.
SoI I'm guessing it could be replaced by a 5$ GPS reciever
the magnets don't directly move the vehicle, the field it generates is just measured by the sensor on the car to be able to get reliably accurate position data iirc
gps definitely can't provide that level of accuracy reliably
or like, the same fucking wires used for robot mowers
I think it runs on a rail - my guess is the red line hides a track that the machine follows.
The red line is pavement. But it looks like there's a bit of very narrow gauge track that the car actually runs on to the left
This is a self driving tram provided by the Korean Railroad Research Institute to this research project. As so often, these “autonomous” vehicles merely follow a special trail that is embedded in the tarmac, often with an indicator colour on top. The rail-ish thing you mentioned is just too far away from the vehicle, and there’s only one.
So only one question remains: is it a car? Maybe.
isn't it the same thing as a car but it just uses magnets rather than paint for road markings
