Please don’t be this person.
With the upcoming snow forecast, consider the reminder that you aren’t the only car on the road. Please for the love of god clean the snow and ice off the roof of your car. Leaving any amount of ice and snow on your roof/trunk is the epitome of selfish behavior. When that chunk of snow and ice eventually comes flying off your car, it can cause serious injury and damage to innocent drivers, pedestrians etc. There is no excuse.
