Running on empty.
If you are running out of fuel or charge, it doesn't make much sense to keep pushing the accelerator.
Yes, it may push the car a little bit forward with whatever fuel is left, but it won't be able to get you anywhere meaningful.
Instead, what would help is to find a refueling/recharging station and let your car recharge (without hustling it further).
Once it's up again, you can drive wherever you'd like to go to.
