Stay with your car as it defrosts

Leaving your car running and unattended to de-ice in snow/frost is risky in the UK as opportunist thieves can steal them in seconds and your insurance won't cover the theft, leaving you uninsured. Always stay with your vehicle, use a scraper/de-icer, lock it, and consider anti-theft devices like steering locks or faraday pouches for keys, or tracking devices to help prevent theft and fines.
