Its just a simple fact that NOBODY outside of F1 cares much about the teams. Why do you think sporscar racing gets no attention? Why the most succesful racing series in the world is all about the driver and puts their numbers in huge letters on the cars?
How are you defining "outside F1"?
If you mean those not working within F1, then F1 fans are outside. In which case, your claim self-evidently fails or this debate would not even be happening. If you mean those who are not F1 fans, then they, as they are not F1 fans, don't really care about drivers, either.
As for the driver numbers, which teams have them in huge
letters? How many pictures of last year's cars can you find with the driver's number prominently on show? In fact, if the driver is all important, why aren't their names in huge letters on driver-centric liveried cars, rather than team-liveried cars with coloured camera-housings being the chief difference between team-mates?
If the drivers were all that everyone cared about, wouldn't they be the recipients of the lion's share of sponsorship money, not the teams?
