How far can I drive with the ABS/Brake lights on?

I have a car in Denver I'd like to drive 1000m to Houston. Runs/drives just fine. I powerbraked it to charge up the HV battery, so pretty sure it has standard brakes. What are the chances it'd make it? I drove another car home from Atlanta, and it had battery issues along the way. probably unrelated, but maybe a regenerative braking issue? Anything about ABS failure make the battery discharge?

 

LOL, I knew someone would ask that. IDK. Usual doofus mode - got distracted, got rushed, and left without getting codes. Then, meant to go back, but got tired of the driving and traffic. Which codes would make it unsafe to drive? I'm thinking if I see no signs of leakage, reservoir is full,I hear the pump turn on and then off with the key on, and the standard brakes seem to work as usual - it's OK to drive home. Kinda like if the fluid controls all seem to be working, I can drive it.
