Today I was driving my employer’s new pool car that includes a touch screen tablet to control many things.
To adjust the cabin temperature involved touching a temperature tab, which brought up independent touch areas to increase/decrease the front passenger/driver set temperature. So you cannot make adjustments on the touch display without taking your eyes off the road, whereas I am able to make many adjustments to conventional controls without the need to look directly at them.
No other touch screen functions seemed intuitive; with the radio playing there was no obvious means to reduce the volume. Touching some other area of the display resulted in a host of icons being displayed (much like on a mobile phone/ normal tablet) – I had no idea what any of them did.
Although the vehicle had an analogue speedometer and rev counter, they were computer generated – so once the onboard computer fails, you will have no alternative but to pay £1,000+ for a replacement.
