William,
I sell Two-way radios for a living and don’t get me wrong a sales a sale. But when your son is 6 years old he should be practicing by himself trying to gain confidence and once you stick com’s in his ear he will be looking to hear advice every lap and could actually become a safety concern.
As a parent i would stay away from com’s while he’s on track it will do more harm than good for a 6 years old. I would just stay off track when there are drivers going twice and three times faster.
Hope this helps….
