If you just want to get the values from hidden inputs just do this. In method rentacar_car type:

car_id = request.GET.get('car_id')
driver_id = request.GET.get('driver_id')
print(car_id)
print(driver_id)

And since you are getting the values from those inputs you have to change method of form to GET.
