City Council Speaker Corey Johnson floated the idea of banning cars along two key Midtown Manhattan thoroughfares Monday, citing the similar prohibition on 14th Street.

“I think the 14th Street bus story is very exciting. I think we should look at it on 34th, on 42nd, on these major thoroughfares,” Johnson said on WNYC Monday.

He called the 14th Street pilot program that limits access to the busy crosstown corridor to vehicles making local deliveries “a raving success,” citing improved travel time for MTA buses using the route.

“It’s something to build on and hopefully will be a model for other places in New York City,” he said.

He said a report is due in November that will provide data about the 14th Street pilot.

City and MTA data show that crosstown buses that once crawled are now moving 30 percent faster, causing ridership to soar.

Weekday ridership is up 17 percent and weekend ridership is up more than a third.

City transportation commissioner Polly Trottenberg hinted earlier this month that the early success could open the door for more busways across the city.

“The traffic on the side [streets] hasn’t turned into the apocalyptic hellscape that critics predicted,” Trottenberg said. “People’s worst fears did not come to pass and I hope it’ll be a template for other parts of the city.”

Johnson’s suggestions Monday came after two New Yorkers called into the Brian Lehrer show with different takes on the car ban and Johnson’s transportation policies.

One disabled Staten Island resident named Lee blasted the speaker’s stance.

“Why are you declaring war on me, on Staten Island, and on cars?” Lee asked.

“There is no war on you, Lee. It’s supposed to make life better for everyone in New York City,” Johnson said.

A second caller, Andrea in Manhattan, praised the pol.

“I want to thank you,” Andrea said. “I adore you, Mr. Johnson, for your fight against the car culture.”
