One of the hardest things to overcome in an interview is a bad driving record, especially a DUI. Interviewers and airlines view how you drive as a representation of how you will fly, and your decision making ability. If I offered you $5 million to drive the speed limit and call a ride-share after a party, would you accept it? Your career as an airline pilot is worth that much or more, most likely. You can sabotage your career by making bad decisions while driving, so please do your best to be a safe driver. Also, if you have some cocktails, a $50 ride-share is a small financial price to pay compared to what you may lose in the long run.
