It's a Beta version so It's basically a near finished test , When they update it they would fix any bugs that may have been found { one Primary reason for a Beta}. But it's also very possible they could decide to add new features.

Their also really isn't a set manual for these things however , if you have any questions you could always browse AF or ask the Community here at AndroidForums

 

Yes beta is more or less a "let's get this out and see how well it works".

Alpha testing is usually closed (not public) which is why most ppl haven't heard of them

I wouldn't expect them to change anything major when the beta is over. A few tweaks perhaps but not to much more then that.

If they did a big change they would have to start the process all over again.

 

No hope for "avoid highways" feature?

I have to have avoid highways. Is there any app in the store with a gps navigation system I can download until Google Maps adds this feature?

 

most of those features wont be hard...especially because our phones use google maps which is constantly updating... total trip speedometer altimeter simple to add...dont know about lane assist but it does show traffic and what not....works really cool if you use aux input on ur car with the fone so u can play music and it will pause the music for the gps to talk kind of cool and factory navish
