‘Let’s go back to college and learn science’ – Pat Kenney tackles Green Party councilor over cars stalled due to 30km/h Phoenix Park speed limit

Newstalk presenter Pat Kenney asked a Green Party councilor if he “knows about the gear” as the two argued on-air about the best way to save fuel in a car.

Changing the 30 km/h speed limit to Phoenix Park should not be discussed as motorists complained that it was too slow, with the presenter asking clerk Michael Pidgeon if the speed limit was also raised for environmental reasons. should be taken.

“You are a Green Party councillor so you are concerned that if you have to drive a car, and I don’t know if you drive a car or not, you should drive it efficiently and in this way save energy and have less pollution. is,” he said.

“And the way to do that is to drive at the proper engine speed.

“If you’re driving at 30km/h you’re in a lower gear, if you’re in a higher gear you’ll face a cutout, but if you’re driving at a lower gear you’re going to have a cutout in the case of your engine. Driving very inefficiently.

“So, how do you square that circle? It’s pure science that I’m not spoofing.”

Cllr Pidgeon disagreed, saying: “Generally the faster you’re going, the more fuel you use,” to which Mr. Kenny replied: “Gearing- do you know about gear ? 20 mph, 30 mph to drive, you can’t do it in top gear which is the most efficient gear to use for fuel saving, if you’re lucky you’ll probably end up in second or third are in gear.

The Green Party councilor then said “this is not true” because fuel efficiency is “not only based on gear, it is also based on the speed at which you are traveling.”

The broadcaster hit back at the councilor again, saying: “Let’s go back to college together and learn what the appropriate science is behind all of this.”

According to AA, lowering your speed can save fuel, as driving at 120 km/h uses about 20pc more fuel than driving at 100 km/h.

It also states that driving faster in lower gears makes the engine work harder and uses more fuel. Therefore, motorists must use the correct gear for the speed at which they are traveling.

“Don’t take too long to get into high gear,” says Aa.

“Driving faster in a lower gear makes the engine work harder and uses more fuel (you can tell by looking at the tachometer next to the speedometer, as it shows the engine’s rpm).

“Most modern cars have a dashboard indicator that tells you the most efficient time to change gears – use that.”

Earlier this week it emerged how government chief whips Jack Chambers and Taniste Leo Varadkar sent angry letters from constituents who claimed the new 30 kph speed limit at Phoenix Park was damaging their car. or forcing it to cut out completely.

The correspondence was among letters sent by the local TD to the Public Works Office (OPW) regarding the availability of parking for Dublin Zoo and the park.

Controversy erupted after traffic chaos around the zoo during the Easter holidays, with some on social media attributing the introduction of safe dedicated bicycle lanes on Chesterfield Avenue to a lack of parking.

In a letter sent by Minister of State Jack Chambers, a motorist said his car cut twice in the park, even though the 30kph limit is common in built-up areas around Dublin.

“I can’t keep that pace because my engine won’t allow me,” his letter said. “It’s causing a very long tailback and if my car gets cut (which happened twice today) the person behind me will hit me.

“Needs to come back to 50kph because my car literally can’t drive at 30kph without stopping.”

In a letter to the OPW, Minister Chambers’ office said it had received “numerous complaints” from constituents.

In a message sent by Leo Varadkar, an elderly component explained how the new slow limit was putting “a lot of pressure on my engine” and “the cars were not built for that speed”.

He wrote: “It’s no fun to drive in the park anymore; It is like an obstacle course and is in slow motion. I think with all these changes the motorist is being attacked left right and center.”
