Even without "parasitic drain" from sensors like for the alarm/keyfob batteries still drain, especially dependent on the weather.They should simply be reinforcing the severity of the problem to allow owners to prepare accordingly. Beyond that, there should absolutely be emergency battery packs that keep the car supplied until proper power can be found. Parasitic drain isn't so high of a load that something fairly small wouldn't be helpful. (Like how emergency packs for cell phones are used)
