id agree leaking steering rack.
will be ok to drive, just if theres no fluid left the steering will be a lot heavier.
may sound stupid. but tomorrow make sure Air con is turned off I noticed a drip from mine a few month ago, and one day it looked like my radiator was pissing water out from under the car from far away, on closer inspection I noticed it was coming from the air con area, and it was just because id had the air con on. may sound stupid, but atleast you can rule that out.
