If you're due a service, ask your advisor to walk you through your safety tech while your car's in with us. It's the easiest time to fit it in, no extra visit needed.
If your current car doesn't have adaptive cruise control, automatic emergency braking or lane keeping assist and you'd like it to, come and take one out for a test drive. It's the best way to actually feel the difference rather than just reading about it. Plenty of what's on the forecourt, new and used, comes with this tech fitted as standard.
You already paid for the tech you've got. Might as well use it, and if you fancy an upgrade, come and try it for yourself.
