GM to cut powertrain warranty to 60,000 miles

Gm is on the fast track for alienating me, I have bought exclusively GM vehicles for over 40 years, some were good some were not. If they think that reducing the warranty by 40 % is a marketing tool then they have to be idiots regardless of what their defenders say. Hyundia has a ten year warranty on their vehicles Now if I were a first time new vehicle purchaser who do you think I am going to buy my first vehicle from?
