Shares of Tesla Motors (TSLA -3.55%) took a nosedive last week after a YouTube video showing a burning Tesla Model S was brought to investors' attention. The video, which showed a Model S engulfed in flames after hitting an object in the road, fed long-standing concerns about the safety of electric cars -- and led quite a few Tesla investors to consider abandoning the stock.

Not to worry, says Motley Fool contributor John Rosevear. In this video, he explains why the Model S fire was no big deal -- and why Tesla's response to the incident speaks well for the company's management.
