It says that your control rig rating is added to your vehicle's speed when you jump in.
Does this really mean that a speed 3 (walk 20 run 40) vehicle in the hands of a high-end rigger becomes speed 6 (walk 160 run 320)? Or am I making a mistake (hardly my first tonight)?

You are correct, that's what the rules say.

Whether or not it should be that way is a topic brought up a few times.

I think it adds to the Speed limit (hee hee) for Vehicle Tests, but doesn't actually increase the speed of the vehicle. There's a quality that lets you speed up your vehicle, I think.

You can also get a similar boost to speed by painting it red, cuz red makes tings go fastez.

And go-faster stripes.

Come to think of it, you can put go-faster stripes on adepts, too. Except that they'd actually work if you get the right kind.

True, but the big babies scream when we use the acid etch paints (makes it last longer).

Also useful for tats for your shapeshifter since normal inks tend to get absorbed and lost.

Cutter nanites also work pretty well, just be careful with their programming.

Speed holes...speed holes

Only if it's WiFi enabled red paint. Cheap shot, I know.

wait is cheap shot a simple or complex action?

Well, simple to type it out, free to come up with it.

only really matters if you GM considers it an "attack" or not...

But Bull ruled that any action affecting the target or causing a roll constitutes an attack and I was possibly taking Pun Damage.

Pun damage is sanity-affecting, luckily there's nothing like this in SR

yet

Give 'em TIme... Canray's probably got a draft or two on it sitting around somewhere.

Cthulurun?

No, that's 'Cthulu? RUN!!™'

Cthulu devours 1d6 shadowrunners per initiative pass.

Unless they have a boat.

If he's running wireless, the boat cant save you.

Speedboat:
Wireless bonus: Outrun Cthulhu.

Unless he starts destroying all reality. Good luck on outrunning that.

You'll get to the next reality over before he's done.

Friends of mine did that once. Admittedly, it was Psion, not Shadowrun.

But they totally started Armageddon. One of them had (two sessions prior) left a note with the GM saying, "Epic use of Manipulation: if my friends destroy the universe, I want to be the first one back." Everyone else got stuck hitching a ride with someone who used an Epic use of The Way* to "be somewhere safe until the universe restarted."

*The Way is essentially traveling. At epic levels you become immune to travel...by which we mean you stop having to do it to get places. The epic use allows the character to go anywhere they desire. This can include "a universe entirely defined by the number 8."
