Why is that? If you never used the ice scraper you wouldn't be able to go anywhere for at least an additional 5-15 minutes while you burn gas idling in order to defrost the windows and who has that kind of time in the morning before work, let alone wants to burn the additional fuel rather than what is necessary for the defrost + scraping the window?
Scraping the windows on the older car never did any specific damage afaik, as plastic is softer than glass.
