For three months you have driven the A76 between Heerlen and Sittard every working day with adaptive cruise control on, without a single problem. How do you use the system from now on?
You trust it blindly: three months without faults prove that you know it
You pay less attention: with the cruise control on, the risk of a rear-end crash is gone
You stay alert: long use does not mean you know what it cannot do
Explanation
False — you mistake habit for knowledge. Research shows that many drivers, even after long use, do not know exactly what such a system is for, how it works and what risks come with it (Book p.218).
