when the touchscreen was being employed were more than 50% longer than standard for some tasks.

This was worse than the 46% impairment found in a previous simulator study

and requiring a confusing number of steps, to boot. In April, after examining the touchscreens in new vehicles, What Car?, a British motoring magazine,
而且启动过程中需要的步骤多得让人摸不清。4月，在检查了新车辆的触屏后，英国汽车杂志《What Car?》报道称，

Carmakers are developing screens that are easier to operate and positioning them more in line with a driver's view of the road.

Haptic feedback, which adds physical, tactile responses, is also coming.

This might, for example, detect a moving finger and produce a clicking sound and a slight vibration when a virtual button on the screen is felt and pressed.
