As has been pointed out, the cost of running a bureaucratic licensing system would make this another impractical.
We should start our own licensing system. Keep it bare bones so that no money is wasted. 100% voluntary, with an annual fee, for a license. No test. A fraction of the money goes to providing the license, the rest is donated to various municipal or state funds for maintaining roads and/or bike paths.
And then anytime someone brings up this idiocy, we tell them "STFU" (Sending the Fees to the USA) ;-)
