Retired drivers and staff

Looking through my shortlist, which I mostly use to put drivers and staff that retired whilst signed with me, I wondered:

How many retired drivers and staff ARE in the iGP database? idk this is kinda a random question, go ahead and throw some guesses here! id say maybe 3 thousand as mine

Id guess a much bigger amount, like 60k
Igp is a decade old  and with the 3 millions of users(im guessing its more too) 
There surely are active teams that have retired at least 2,3 drivers each and lets not talk about the bot/inactive teams haha

After some quick detective work, I've got a decent answer:
At time of writing there were around 13,555,000 drivers in the game.
(Source: This driver (ID 13565207) was the most recently created when I checked, and around 9600 drivers from ID 1-9600 are missing)

Woah, thats alot! I thought they would, after some time, delete old retirees from the database. Seems like they keep the old drivers from 2016 here, even if retired! (ngl that kinda sounds unhealthy to keep unnecessary driver data on the database)

About this. Can you find the link to the driver with ID 1?

Drivers 1 to 9558 aren't present. The first driver present is This one (9559) - Created in 2012. I've no idea why 1 through 9558 aren't there, only staff would know.

Thanks. Weird cause that driver is also retired 

Maybe drivers created from 2011-2012 were erased coz they changed or overhauled it? That would be my guess.

I can still find so many drivers from 2011 on my transfer market
