Things I like : automatic loading bay, simple yet efficient, details : winch and cord to secure load, adjustable high for loading, the functions are clever.
Thing that should be better imo :
steering wheel make several turn, it should be 1/2 turn
if you are only on front drive or rear drive you are forcing on the second motor, let's pair them or make them unclutchable
accumulation of beams for bodywork isn't good looking, let's find another compromise, ( for exemple snot lego system if it's your choice )
