In addition to cops, I'm also concerned with other drivers. Getting pulled over is a hassle regardless of the outcome and I don't really feel that it's my job to educate my local LE about my perfectly legal activities. So, I try to keep my vaping on the low while driving and especially while stopped at intersections to avoid having my tags called in by an overzealous concerned citizen. People generally fear what they don't understand so I just play it safe.
What a jack ###. I have tried for nearly 2 years to get the opportunity to educate my local cops but they never seem to care how big my Mods are. Thanks for taking one for the team and good job keeping your cool. I would have gone to jail in your shoes
