[Batman] How does nobody see where the Batmobile or Bat-copter or Batpod comes from?

Now I know different adaptations place Wayne Manor / the Batcave in different locations, and therefore different distances away from the city, but come on! 

From what I understand, if Gordon or someone in the police really wanted to, they could just mark down where it comes from and the last place it was seen and within like a month, somebody must notice: “wait a minute, all these extremely badass advanced combat vehicles seem to come from the same direction as Bruce Wayne’s place, who just so happens to be extremely rich and connected and could probably obtain those vehicles, which would make sense considering his dad’s line of work!”. 

Some adaptations even go as far as putting Wayne Manor on an island or literally right outside the city. Nobody’s taking a stroll or walking home from the club when they see a futuristic tank lookin thing jump out of a waterfall? Nobody’s doing a little night photography of the city line when they see a large black object bust itself out of the basement of the richest dude in Gotham?

Ding Ding Ding. Almost nobody left actually *wants* to blow the Batman's cover.

Early in Batman's career, what you're talking about would have been a serious risk, since he was up against an immensely corrupt police department, City Hall, and a number of conventional mobs. All of these groups would have had a vested interest in hunting Batman down and killing him as efficiently as possible, without showmanship or the typical comic book runaround.

 However, it took all of these people too long to *realize* that they had a vested interest in doing this. Batman didn't break out the full extent of his resources for quite a while; he stuck to street crime in order to cement himself as an urban legend, and he kept the higher-level investigative work against the Mob and City Hall quiet enough that they didn't realize the full scope of his ambitions. He was viewed by the elite as a petty annoyance who could boost the public's morale while they fleeced them. By the time they realized they needed to take him seriously as a threat, it was too late; he'd already set their downfall in motion.

In the modern era, with supervillians and the like, there are surprisingly few people who actually *want* Batman's ID out in the open, and there are even fewer with the resources to publicize the story if they do find out. The GCPD isn't going to blow his cover. Most citizens of Gotham like the guy enough that even if they stumble on something like the waterfall or the secret tunnel, they're going to keep their traps shut. Most investigative journalists have given up on trying to nail him down because the cops stonewall and Batman runs misinformation campaigns. A lot of them *suspect,* but you can't print a suspicion.

And amongst Batman's enemies, quite a few of them do know, for the reasons you described, but they all have reasons to keep it to themselves. Joker and Riddler don't want to spoil the fun. Ra's Al Ghul respects Batman as a person and doesn't usually try to make his life harder outside of what's necessary to make his plans work. Cadmus and the SHIELD- style intelligence agencies often know but they like the stability Batman brings to Gotham and the superhero community at large. The rest either don't care enough to proactively go after Batman if he isn't interfering in their current scheme, or they like the stability he brings to the underworld (I can't remember the last time Penguin seriously tried to get rid of him, for example.)

Also, in Post-crisis continuity Wayne Industries came out and said, "Yeah, we're funding the Batman, he's using our tech and our facilities. We've got more lawyers than you, bring it on." That threw up a pretty significant smokescreen against the prospect of Batman being Bruce Wayne specifically.
