Are electric cars toxic?

My Kia Optima wouldn’t start for me this morning. It was really cold, but that shouldn’t keep my car from starting. It’s only four years old, and it never had a problem starting in the cold before. What could be causing this?

My younger son, who’s four, has begun protesting when I put him in his car seat. He says he wants a booster seat like the one his older brother has. When can a child travel without a car seat?

I had my car parked on the street to go into a business. When I came back out, someone had poured paint over the hood. Will insurance cover the cost of this?
