Yeah you can already get the drivers license integrated. They're incentivising it by making the renewal fee higher if you want the actual license card. I'm not sure which I will choose next time I renew (or if it will even be an option then).

The one thing I like about the my number card is you can have your alias printed as a memo on the front. Basically, if you can prove you use a katakana name, you can have it added. Mine doesn't include my middle names, which is very useful when needing ID for making a credit card etc.
