Transformers the Movie Ending: WTF?

Okay, two questions about hte very end of Transformers. slight spoilers.

The guy and the girl eventually get together. So the VERY last shot of the movie, they are making out on top of the car (Bumblebee). Remember: it's not a car, it's an alien, it's a person. I mean they take pains to show that the Transformers have feeings. Anyway. They make out on top of the car. On top of their friend... while the other transformers WATCH!!! I mean how sick is THAT?

also: I almost laughed wine out my nose. Bumblebee (the car) can't talk throughout the whole movie, He uses the radio and clips from the radio to get across his messasge.  Big fight, everything is okay. Bumblebee says "I want to stay witht he boy.".  The response "You can TALK?!". And that's it. yes, it doesn't make sense, it's totally incongruous with the story, but ify ou point out the continuity eror, somehow it's not an error.

anyway: Fun movie, but way too long. Could have done wihtout the whole Australian teen who figures out he hack.  An aside, how pissed of is that actress thinking that she was going to be the resident hottie.  What else? Do grade 11 kids look like that? Hell, I didn't. The guys didn't. And the bully... only 2 popped collars cool.
