"The hardest part for me would be the lack of camaraderie with other drivers," Michael, a driver in Las Vegas, told Business Insider in an email. "I see them as my competition. I wish them well, but just not at my expense."
"So due to my lack of communication with other drivers it does get lonely while on the road; as a result, since I'm driving in Las Vegas, there will be days that I'm not in a good mood and since my passengers are tourists, on vacation having a good time, it can get hard to drive."
