"Lockdown" is funny. As others have mentioned, the problem is not with the software itself, but the data... It will be fine in the long run, but there is no quick fix.
I wouldn't depend on the Apple's Maps improving much just because there are a lot of people using it. Yes, its supposed to collect statistics for stuff like traffic, but it has no way of fixing street names, correcting errors or adding business unless users do it manually. How many people are going to do that? How many people even know how to do that?
A desktop counterpart to Apple's Map's should have been released at the same time also. I feel like people would be more willing to make corrections on things while at home rather than on a mobile device while they're in the middle of getting to their destination. Apple's maps existing only on iOS devices is a big disadvantaged, it needs a web-based counterpart.
Really, this is new territory for Apple, they haven't offered any services that require the amount of data collection that goes into a projected like this. Google Maps are the best because they are the best a data mining.
