It depends on the architectural style of the house
My mom-in-law has a vinyl-sided house with a wooden switchback ramp in the front. In her case, I think the concrete ramp would look better because her front and side porches are concrete with metal railings.
The houses of the neighborhood in the story are new. Maybe a couple years' worth of mature landscaping could soften the look of the concrete ramp.
Maybe they thought the upkeep would be easier with concrete.
Not necessarily. Many of the new construction 2-car garages are smaller scale. We have an older 2-car garage, which is bigger, and still my Hubby's work van barely fits inside. He has to pull all the way in, almost touching the back wall, and then he can barely close the garage door. He can't get into his van unless the garage door is open. Also, he had to deconstruct the garage door opening to make it taller than normal in order to fit. Still, he always enters the garage with a full tank of gas. Otherwise, the top edge scrapes the trim.
My son-in-law has a brand new house with a 2-car garage. It is shorter than our's, and his driveway is more narrow. He has a Denali SUV and he can't park it in the garage. Even if he pulls it in all the way, it still sticks out about a foot from the rear.
I imagine a lift-converted van might not easily fit into their garage, and most likely doesn't have space to operate the lift within the garage.
Wow, that's so immature!
