Much has been made about the promise of autonomous driving, with some enthusiastic experts claiming it will be the status quo within a decade. And for some motorists that moment can't come too soon, as the technology will surely make it so much easier to get from A to B to C than it is today. But until then, people can still focus on some existing hands-free driver assistance systems that are a nod towards autonomy, and you can find some of those systems aboard used cars today. While none of them will turn a privately owned used car into the equivalent of a robotaxi, they could yet make driving easier for the used car buyer. Although it's definitely important to look carefully at the entire package before buying one of these suitably-equipped cars. The Journey Starts On The Highway Most people who have tried a hands-free system tend to be quite impressed at first exposure. When the system is working properly, the car will settle into its lane, keep pace with traffic, monitor the driver's eyes, and handle those small corrections that can sometimes make long highway drives so tiring. These systems certainly don't take the driver out of the picture at all, but they can make a 300-mile interstate run feel a lot less demanding than it might with just cruise control. As these systems are essentially meant for highway consumption only, it stands to reason that the best candidate cars will likely be those that their manufacturers have designed for highway comfort rather than back-road thrills. When such cars have the correct equipment on board, they can feel meaningfully more relaxed on the average main road. And while they won't solve every driving scenario, they can reduce fatigue in the most predictable part of driving, especially when
