First, as review of the Escalade Hybrid in The New York Times points out, even a hybrid uses a lot of gas if it's huge.
"...its mileage is great compared with a regular Escalade’s, but that’s like saying the American economy is great compared with Zimbabwe’s."
The reviewer estimates it at about 20 m.p.g. overall (compared to 12/18 m.p.g. for a regular Escalade.).
Still, the lack of any real fuel efficiency isn't the main reason that these ridiculously large vehicles, which my kids appropriately call Monster Cars, should be retired, along with executives at the companies who made them.
They're not safe. Not for drivers, and not for pedestrians.
Teens shouldn't drive 'em; studies and officials and cops say; they require extra good driving skills because they're so unwieldy. In a collision with an SUV and a car, guess which passengers are far more likely to die than in a mere car-hits-car scenario? And guess how much car insurance rates have gone up to cover these unfairly-weighted accidents?
And who can forget the little girl mowed down in her driveway by her own brother, who didn't see her out of the rear window of his SUV? Guess what: It happens a lot. Do an online search. Toddlers; kids, dogs; even parents, killed in driveways, car washes and parking lots.
This clearly overrides the benefit of being able to drive home an entire baseball team. If you need that, hire a team bus. "Cars" like these should not be driven by folks who don't have a trucking license.
On a personal note, coming from a person of petite stature: I can't see beyond you, Monster Car, to turn into an intersection. I can't see cars coming from behind you if you are stopped at an intersection, in the middle, trying to make a left-hand turn (because drivers of said Monster Cars tend not to be retiring, polite motorists). I have seen you blow over taffic cones at school pickups, oblivious, even though the cones are about the height of the preschoolers standing right next to them. I have seen you almost back into me and my kids in a parking lot (twice).
The Verdict: In short, Monster Car, hybrid or no, you present an overwhelming danger to myself and my family, and as such, you must be destroyed.
