I Could Drive to My Age Once, Anywhere

I could once drive to my age,
Anywhere, in any state,
Within the law.
But now just in Texas,
Can I drive to my age
On a couple of stretches
And not set off a radar gun.*
On the other hand, there’s the Autobahn,
Where a driver’s age, even triple-digits,
Will not exceed the speed permitted.**

*Texas allows 85 mph on a few roads.
**Top speed on parts of the Autobahn is 155 mph.
