Hi I’m new here but I thought this community might be able to give some solid advice. I’m in an area hard hit by the ice storm this weekend and I’m going on 3 days at home with no power/heat at home and at work. Temp inside my house is 36° and temps are falling into the low teens tonight. I’ve spent most of today hanging out in my Honda Element with the car running to charge my devices and stay warm. Would it be safe to sleep in the car with it running? I know this can my dangerous in certain situations. What would minimize the risk?
