Almost half of drivers are seriously distracted by in-car technology while on the road, an RAC survey has found.
As many as 55% of those aged 17 to 24 have their attention taken from driving, with radios and CDs the top distractions.
About a third of all drivers are seriously distracted by satnav systems or mobile phones and 35% by using heating and air conditioning.
Some 85% of 1,034 motorists asked said drivers should be taught how to use in-car technology properly.
Anti-locking brake systems (ABS) and immobilisers are fitted on new cars by law, yet only 70% of motorists knew their cars had ABS, while only 68% knew there was an immobiliser.
In the next 20 years of motoring, 23% of drivers surveyed said they thought cars will have technology that means the driver can input a destination and sit back.
RAC technical director David Bizley said: "In-car technology has come a long way since the late 80s. The advances have fallen into two camps.
"Active technologies such as in-car entertainment are not always positive as they can cause driver distraction, while passive technologies, such as anti-locking brake systems, are undervalued as they are not fully understood."
