Some people may employ chauffeurs full-time to drive them in their vehicles, while professional services offer on-request limousines or rental cars that include chauffeurs.[4] This is similar to but much more luxurious than taking a taxicab. A variety of benefits are cited for using chauffeurs, including convenience, productivity, and time savings,[5] and driving safety for business people[6] and seniors.[7] Insurance costs for luxury vehicles are often lower if the designated driver is a chauffeur.[3]
