Driving the Jet(ta)

I have to drive my son's car for a few weeks. I've driven a Suburban for the past 23 years. The Jet is different. First I get in, start the engine and then accidentally wash the windshield, because the gearshift is on the floor and not on the steering wheel. There is so much room in the garage! I pull in and can walk all the way around and have room to spare. The big difference is the acceleration. The Suburban has power, but whatever added on air intake thingamagigger my son had put in makes his car take off like a jet and sound like a jet doing it. You can experience G-force if you're not careful. When he wanted to put it in he told me it would "improve engine performance" I had no idea it would improve acceleration. I do not think it is good for a young boy to have a car that zooms like that. I hope he is being careful - are you reading this Buddy? I am taking very good care of his car for him and I hope he is taking good care of mine. And not ever speeding in it.
