At the Labonte home, Bobby Labonte is the boss, and Alexa is the servant.

Alexa, in this case, is the intelligent personal assistant developed by Amazon. If Labonte wants his television on or his lights dimmed, all he has to do is tell Alexa.

“It’s part of what I’ve done for years,” said Labonte, who lives near High Point with his wife, Kristin. “In racing you have data simulation and you’re working to trim one-tenth off a second off each lap. You’re trying to do something most efficiently.”
