I like how people are defending the Rigger position, by pointing out all that is wrong with Riggers.

"Car Thief" Rigger, "Hack the Car." That is a non-starter in 5e. Zero percent of "Rigger gear" has an Attack or Sleaze Rating. Meaning the Rigger either has to shell out huge amounts of Nuyen for a Deck, or use one of two workarounds. (A dongle for their commlink, or Persona Firmware mod a Stealth Tag.)
Then, the Rigger has to dip into a skillset that isn't theirs to do the hacking.
Unfortunately, Hacking is pretty much required, unless the Rigger wants to use an extended Hardware Test to disable wireless. And that might be a skillset outside their own, depending on build.
"Technomancer with Skinlink" as Car Thief Rigger. Thank you for acknowledging that Techno's are better at Rigging than Riggers. It reads as if this won't improve in 6e, as Banshee has stated that Technos start out of the gate of CharGen as fully functioning Deckers with the neat tools that are Techno only (Complex Forms and Sprites.)
After one, maybe two Submersions, the Techno is a baby Rigger (unless 6e has changed the dynamic a lot, more than enough to fill the roll of Rigger) that can grow into a full fledged Rigger with enough Submersions. (Probably 3, maybe 4.) All the while, never giving up full Decker and the neat stuff that is Techno only.
I still have to see what all was done with Riggers, but right now it reads as if Riggers are still the trash Archetype.
