Auto accessory shops are reporting a more than 10-fold jump in sales of hands-free devices for cell phones ahead of a ban on phone use while driving that kicks in Monday.
The shops are devoting twice the usual shelf space to such gadgets.
"Most buyers are people who drive cars for business, like sales reps on the road," said Masato Uchida, a store clerk at auto accessory shop Super Autobacs Kawasaki.
