My my, much covered in a small area (And my first post in, wow, forever.)
Right then!
Firstly, in older games, we *usually* had a Rigger, but not always. Only two players ever tried them, however, and if neither was in the group at the time, or had decided to play something different, then we had no Rigger. Back then, their job was to sit in the van and wait. Kinda dull and boring. Yes, they could have had drones and so forth, but none did. They did lots of RP during the legwork section, but once the run started? "I'll keep the engine running. Have fun storming the castle!"
Deckers, meanwhile, were 100% NPC across the board. "Johnny, get the door open and get those cameras off." "On it." ... ... ... "You're clear." Nobody wanted to deal with the solo adventure aspect of a single Decker and, in truth, after they got the 'Taint' on them due to that, no one even bothered to *learn* the decking rules for later editions. This continues to be a problem today, with no one locally being able to understand the 4th ed ones. We'd love to HAVE a decker, but there's still a dozen versions of "How do you hack open a door?" answers, so, we're still on pause and still using NPCs for it. (No, don't derail this with a big Decker thing. We'll all be stabbed.)
On RaceAs for Elves, they come and go in waves. Some players take them, either because A) they're Elf Fans or B) they're gunbunny types who just *have* to have that reaction. A Charisma-based Elf is pretty much unheard of here. Yes, they talk with great skill as a faceman, but, prejudice being so common, having your only talker sidelined when meeting, say, some Orks? That's crippling. Humans, being the centerline, tend to work better, even with the lower Charisma. (And no Pornomancers, thank Gwar.) So, we get some, but not many.
Orks used to not exist. Trolls, sure, but never Orks. "Why bother? They're like Trolls Lite! Please." These days, however, they're everywhere. It's hard to find a combat-side characetr who isn't a Metahuman instead of plain ol' human, now, with Orks having a significant lead. Trolls are simply too rare to not get hassled in the good parts of town and those fake liscenses just don't hold up when Lone Star finds you toting around a rocket launcher a half mile from a Shiawase facility, you know? The big guys just can't hide anymore, whiel Orks blend in easily. (Can you describe him, ma'am? | Well, he was an Ork. | ... Well, that's got us down to three million suspects. It's a start.)
On Long CoatsRarely seen, aside from Mages (Shamans sometimes, Hermetics *always*) and teh rare Matrix-fan Gunbunny. Most stick to armored vests (If combatty), vests (Pretty much evryone), or Jumpsuits (If on an active run) ... jumpsuits, in particular, are beloved by all. Skintight, armor plated, look post-modern, and then get tweaked out with electricity resistance, a chemical-proof helmet, and off you go, *stylin'*.
On a quality rideThere's a team van. There's *always* a Team Van. Bulldog's parent company must have some of the most valuable stock in the world with how much love Shadowrunners give them. They're, like, the official *sponsor* of Shadowruns.
Bikes pop up sometimes. Street Sams sometimes (The sleek n sexy ones, not the big chunky muscleguy types), gangers, but that's it. Eurocar Westwind also makes a rare popup, but I have to give mad props to oen group who went to all professional-style meets in a rented limo. Normal meets? You creep around and look normal, but for teh BIG stuff? Drive in style. Impress the Johnson with your own professionallism. Just try to keep the driver quiet about it being rented instead of owned.

Bikes allowed team members to go do things without the van, which allowed them to seperate.
MOST runners, however, never bother to buy a vehicle, assuming that they'll just ride the van everywhere. They wind up having to take a taxi or trains. Mind you, having a Troll Sammy trying to ride to the meeting on a train, while wearing full gear? Not the wisest of moves.
