But they removed them well after they showed they could accurately predict distance with vision.
LiDAR doesn’t make sense as a sensor to me because it only works in good weather. Its Like a car without windscreen wipers.
Appreciate the downvote/disagreement.
But here is Karpathy explaining how vision can be used to measure distance to objects accurately[0]
Here is the fact that LiDAR doesn't work in the rain[1]: "... In heavy rain, for example, the light pulses emitted from the lidar system are partially reflected off of rain droplets which adds noise to the data, called 'echoes'."
Which logically implies you need to revert to vision, as see [0] also for why Radar is unreliable.
