CAR TALK: There's a reason why cars don't have brake lights in front
DEAR CAR TALK : Why do n’t cars come with brake lights on the front man end american samoa well as the back end ?
Seems like that could prevent a set of accidents at four-way stops, at crosswalks and at streets with left turn lanes .
— Mary
DEAR MARY: It ‘s an concern estimate.

It would provide utilitarian information at four-way stops. It would let pedestrians in crosswalks know that a driver sees you and is slowing down. And it would let an onset motorist know that a person making a left turn sees them coming and is waiting before crossing traffic .
There are two likely downsides I can think of. One is that if you put brake lights on the front man of the car, at night, you would n’t know if a car was coming or going. And if you think bibulous drivers are a menace immediately …
Imagine seeing headlights and brake lights at nox and not knowing if it ‘s two cars or the same car. immediately imagine that in the rain .
I suppose you could address that by using a unique signal — something other than a crimson light. But that leads to the second base electric potential drawback : information overload .
Drivers are already processing a lot of information when they drive — assuming they ‘re paying attention. And right now, the signals from early cars are pretty square. You ‘ve got headlights, which means the car is coming at you, taillights, which means the car is traveling in the same direction you are, brake lights for discontinue, and turn signals. Add another light sign to read and it ‘s potential you could confuse people .
possibly not. But rest assured that a change like this would not be made without years ‘ worth of study and research by the National Highway Traffic Safety Administration and the Department of Transportation. They ‘re abhor to make changes like this unless they have proven, real-world value. And no negative effects on safety .
The other factor is that, increasingly, we ‘re giving up on humans and turning over the decision-making to computers. The stress right now, rather than adding information for humans to serve, is to take human brains out of the equation .
That ‘s why there are nowadays condom systems that detect pedestrians and stop the cable car if the driver does n’t. And systems that stop the car if you pull out from a four-way catch and are heading toward another vehicle .
In the not besides aloof future, cars will communicate directly with one another, letting a nearby car know its proximity, direction and rush. And automatically transmitting an abhorrent gesture on your behalf when another car ‘s calculator cuts off your car ‘s computer. Is n’t life august ?
DEAR CAR TALK: Please settle a contentious refer between my conserve and I .
He is an electrical engineer who is never wrong, and I am a housewife who values her pride and is tired of being embarrassed in public. We have agreed to abide by your decision, although I think my husband may renege on this agreement if you decide in my privilege !
We have a 2017 Volkswagen Golf, a 2016 Toyota Tundra and a 2019 Subaru Legacy. The business is my conserve ‘s belief that driving these vehicles during the hot summer months for more than 10 miles necessitate raising the hood after parking the vehicle, basically to “ let the heat out. ”
If we go to the grocery store store, he raises the hood in the park fortune. If we drive out of township, he will raise the hood at the remainder stop and again at our address. If we drive 15 minutes to go out to eat, he pops the hood at the restaurant. I am tired of courteous, refer strangers approaching us to see if we “ need any help. ”
surely in this day and age, cars and trucks have fans or refrigerants that will mechanically help cool the engine when a vehicle is stopped !
If you say this exercise is dear for the car or truck, I will swallow my pride and try to accept the fact that we are the only ones ever to do this, wherever we go !

Love your advice and your newspaper column. Thanks for your thoughts .

DEAR BECKY: We feel for you, baby .
You ‘re absolutely properly. The fact that cipher else on the planet except Hood-Up-Henry does this ( and no manufacturer recommends it ) is a pretty good clue that it ‘s 100 % unnecessary .
car engines are designed to run hot. They have robust cooling systems and fans that are designed to come on even after the car is shut off, when necessary .
But unfortunately, you married an engineer. And engineers focus on the theoretical .
even theoretically, the engine itself — the pistons, crankshaft and valves — is unaffected by how long it takes the heating system to dissipate. But there are rubber eraser belts, seals and hoses whose lives could be extended by ( according to our detailed calculations ) up to 11 minutes total over the life of the cable car if he dutifully raises the hood after each and every drive .
Is it worth it ? No. I would say merely in marital discord, he is already on the fall back side of the ledger .
then you factor in the wear and tear on the springs, hinges and pistons that hold up the hood, the hood latch and the hood latch cable, and the dry-cleaning bills from the dirt he gets on his restaurant clothes, and I ‘d say he ‘ll never catch up, no matter how many minutes of life he adds to his belts and hoses .
But as you wisely — and probably correctly — predict in your letter, telling him he ‘s theoretically right but much all wet is not going to get him to change his demeanor. For that, you may have to resort to trickery .
here ‘s what I ‘d do. Next time you two have restaurant reservations, pay some neighborhood kid to stop by while you ‘re eating and steal the battery .
Your husband will acknowledge that his hood-up habit just cost him $ 90. But he ‘ll argue it ‘s a fluke and that he ‘s still saving money in the long run. therefore, a month subsequently, pay the kid to do it again .
That ought to persuade him that there ‘s great profit to keeping the hood latched and closed in public places .
If not, we give up, Becky, and all we can offer you is our admiration and sympathy.
