CONCORD, N.C. -- Every Thursday, we're going straight to the experts all across the Hendrick Motorsports campus to get your questions answered.

From drivers and crew chiefs to engineers, mechanics, pit crew athletes and more, every department is chipping in to answer fan questions sent our way on social media using the hashtag #WhyDoYouDoThat, with a new video posted each week.

This week, Alex Bowman provided some of the reasoning behind why drivers occasionally swerve back and forth on their tires before taking the green flag on a restart.

Since the last time we checked in on the series, we've also gotten questions answered by No. 48 team crew chief Chad Knaus, assistant strength and conditioning coach Evan Kureczka and composite specialist Kyle Walker.

Check out some of the other recent episodes below, and you can watch them all on the "Why Do You Do That?" playlist on YouTube.
