In CA in the 60's, you could get a learners permit at 15 1/2, which would allow you to ride a mororcycle alone or drive a car with someone over 18.
I’m just old enough to get in under the change. Driven for 14 years, they changed it the year after to make kids wait until 18 for learners and 21 for full.
I’m surprised the boomers haven’t raised the voting age yet.
