1. Tesla cars don't have gas tanks - they run on electricity! This means that you can charge them up at home or at a public charging station, and you never have to worry about running out of gas.
2. The only downside to this is that Tesla cars can be a bit more expensive to maintain than traditional gas-powered cars, since you need to regularly charge them up rather than just filling up a tank.
3. But overall, Tesla cars are a great alternative to traditional gas cars, and they're becoming more and more popular every day.
