Agree, it sounds like the days of driving/taking care of your own car are done, sell the car and use the proceeds towards Bolt taxis.
Hiring a driver/mechanic on-call for just a few hours a week and then paying them less than a Bolt driver isn't going to go over well. Either sweeten the deal by hiring a personal assistant, maid, driver, cook, shopper, errand runner or use either Bolt or public vans & buses/10b songthaews.
