Let him drive it! I remember the first time I drove a vehicle. It was my mom's 2002 Dodge Grand Caravan. I told her I'd pull up to the mailbox so she could get the mail. I quickly found out that you can't get the mail out of the mailbox at 40mph. One busted mirror, cracked windshield, and slightly injured mom later, I was grounded and wasn't allowed to drive until I got my permit in 3 years.
