They are an electrocution hazard, the voltage on a string of panels is several hundred Volts, enough to die. One can build a fool-proof system, but the current devices and connectors are meant for static configurations handled by a qualified installer. You can DIY, but most people cannot do that safely.
Also a 500W panel is ~ 20 KG (~45 pounds) and an MPPT can exceed that weight. For a car with a battery that is tens of KW, any portable system that is less than a few KW is not very useful, charging the car 5% per day is not feasible for most.
