Emergency Brake Assist would help if the van was equipped with it. Swerving at the last moment and without warning would not be possible because EBA would activate brakes earlier and you would be able to see van's stop lights.

Calculation of battery capacity one can build for 34B 0.3k$ per 1kWh of battery storage [1] (0.3$/Wh) Battery capacity = 34B$ /(0.3$/Wh) =113.3GWh (1G$=1B$) The 34B battery capacity will be equivalent to 113hours of operation

It looks like availability of good quality training sets will be a stumbling block for LLM use in Verilog chip design since pretraining with other programming language corpus is not transferable. (see below for quote from Nvidia paper) A lo

Hardware function implementations deal with multidimensional design space metrics: performance (speed), power and area. These should be taken into account in any work intended for more than just digital design basics. This paper provides a

Same here: Honda CR-V 2020. It uses single lens (so not a stereoscopic vision) and radar. Never did it brake hard, only warning and few times brake pretension. It will occasionally give false positives on a street curving left with cars pa
