When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion.

Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar).

Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it.
As vision processing gets better, it just leaves radar far behind.
These things are best thought of as probabilities. There are 5 forward-facing cameras. It is highly likely that at least one of them will see multiple cars ahead.
