I'm afraid the days of a telescoping steering column are over the safety reasons.
highly unlikely, there are tons of models with them, most are power and tied into the memory functions. Saw it in a lot of cars at the Los Angeles Auto Show.
Caddy has it in the CTS (both coupe and sedan) STS and DTS, I've driven all 3 in the past year (2010 and 2011 models)
Chrysler has it in the new 2012 300c and 300c SRTs
Dodge in the Chargers
Jeep Grand Cherokee
Lexus in the ES, GS, and LS vehicles
All Lincolns and Several Fords (Taurus, and Edge)
Higher end Mazdas
Hell even the Scion TC has one..
