@carmummy: Reading glasses left on a car dashboard in direct sunlight can potentially cause a fire. This is because the lenses of reading glasses can act like a magnifying glass which focusses the sun's rays onto a small point. If that focused light falls on a combustible material it could ignite and start a fire and you could come back to your car burnt to smitherines 😅🔥 #carsafety #roadsafety #newcar #carshopping #carreview
