Vehicular Accidents

Hindi ko napanood tong part na to, but indeed it didn't make sense.

Start at 6:20... mapapa-roll eyes ka talaga. https://youtu.be/qmjV0tBa-oc?si=HBylVCrYb3Qj1fVp&t=380

Yung vlog niya lang explaining the movement of gear teeth during N and during D yung may sense sa explanation nya.

The way he characterize what people are doing (D-N-D-N...) is parang ginagawang fidget toy yung shifter. Hahaha.. Hindi naman ganun in reality.

All jokes aside, there is some sliver of truth that unnecessary shifting adds to wear.... but it is nowhere near the potential catastrophic results he is preaching. Off the top of my head, these are the only times that friction materials wears out:

1. During engagement and/or disengagement, due to a very small amount of slippage
2. When you overload the vehicle and/or if you frequently do aggressive acceleration
3. If you don't do regular maintenance, use of the wrong ATF, or if the ATF level is incorrect/low

Once the clutches are locked together, there is essentially no slippage (unless no. 2 and/or 3 conditions are present, which will cause them to slip early until they burn out). Solenoids, like any part can also fail due to certain things (burnt out coil or due to dirty ATF), but it will normally switch all day without issues.

So in the grand scheme of things, wear caused by No. 1 is practically negligible. In fact, the A/T does automatic shifting on its own dozens, even hundreds of times as part of its normal operation everyday. That means, clutch packs are continuously engaging and disengaging, caused by ATF pressure supplied by different solenoids, so it can give you the correct gear for that particular driving situation. This is all by design.

So to summarize, occasionally switching between N-D at traffic stops, if you do it, adds a very insignificant wear to the clutch packs, relatively speaking. Most A/T failures are mainly due to No. 2 and 3... and especially No. 3.

--------------------------------

Sorry for the OT, but let me add an insight into that Nissan accident....

I speculate that the driver fell asleep then na alipungatan, somehow switched to the wrong gear and the rest is just the result of sheer panic.

[dr. d]

i'll still continue slushing that stick while i drive in stop and go traffic. bahala na the amount of wear i will tear into it, every time i shift that stick.
after all, it's there for my convenience.
pa-ayos kunalang when and if the time comes.
heh heh.

[Tha_Mann]

Dyan maganda iyong EPB na may auto brake hold.

yup, laking tulong nito. pero pag singitan na traffic eh off ko ito haha.

I only switch from D to N pag super heavy stop and go traffic lang naman pag na feel ko nangangalay na ako from stepping on the brake. Bihira naman mangyari yun. Mas natatakot akong mangalay at dumulas yung paa ko sa brake and hitting the car in front. Mas masama naman kung yun yung nangyari di ba?

Tingin ko rin the wear is negligible. It'll take someone years and years of doing this, proabably more than the expected lifetime of the car before masira mo yung transmission doing that.

[dr. d]

perhaps putting it in N or P, then engaging the handbreak, will result in less tired break foot, less transmission wear, and even less break pad wear... ?
also, the vehicle is more secure in its stopped position.

Agree. Kahit anong galing mong driver, the smallest distraction could set off a sequence of events that can make you a safety hazard to other motorists. Sometimes in our boredom, we fiddle with stuff during stops like working the A/C, the radio, pick up items that has fallen on the floor, etc. Holding on to the brakes while in Drive is perfectly ok but it comes with it the presence of mind na hindi mo bibitawan yang brake pedal ano man mangyari inside the car.... like matapunan ka ng coffee/food, may pumasok ng langaw, may dumapung gagamba.... things of that nature. Kaya for longer stops, I put it in Neutral + parking brake, then I'm free to do anything I want, within reason of course.

one possible dis-advantage of keeping the foot on the break during nighttime heavy traffic stops,
"nasisilaw ang motorista sa likod."
some cars' rear break lights are more ghastly than others'.

lalo yung mala disco lights na MONTERO, FORTUNER, EVEREST, TERRA, etc.! actually mas nakakasilaw pag binitawan nila preno kasi nagiging white yung kulay ng lettering.

So far, *knock wood* hindi naman ako nasisilaw sa mga naka set up na ganyan. Maybe it's the rake ng windshield ng mga kotse ko is not too sloped, or baka dahil naka light tint ako sa windshield?

Mas na bother pa ako sa mga naka overpowered na mga headlights...

ah yess...
LED-ize the bulbs, but not the reflectors.
there should be a tightly-policed policy on this. they are real traffic hazards at night!
and include the two-wheelers, please!

the early 2000s camry comes to my mind.
the first time i got behind one such car, the brightness of his break lights surprised me.

and what about the tall delivery trucks with green or red lights at the top corners of their trucks' rears?
at times, i am confused on whether the stoplight is green or red...

and the long cargo and fuel delivery trucks!
their small headish-lights pointing backward are blinding at times.

lastly, slex.
for some reason, the workers doing nighttime work at segments there, point the work lights onto the work surface, but also into the eyes of oncoming traffic.
nakaka-silaw!
can't they point those lights in the direction of traffic flow instead?

Dati na iirita ako sa reverse beep beep sound ng Raize sa reverse gear. Part siguro ng backup sensor. Ngayon ok na din pala, pang extra safety reminder sa driver na nasa [R] ang gear.

is the beeper inside the driver's compartment, or is it outside the vehicle?
kasi, if it's outside, it's designed for the pedestrian.
bonus na sa driver kung maging reminder niya.

It is typically inside. I had it as factory on my 2KD A/T Innova, but missing in the 1GD Innova.

FWIW, the beeping wasn't annoying. Anyway, you'll only be on reverse typically for just a few seconds to maybe a minute, at most. It was a good audible cue that gave no ambiguity on what your vehicle is setup for... which is reverse.

as an aside,
i have this 2015 altis V.
initially, its proximity sensors were driving me nuts, what with the various plants lining our long driveway that we regularly reverse from, as well as the myriads of motorcycles filtering in between us cars during stops.
i turned it off, but later turned it on again, as i found out i was missing it. "it has its uses".
heh heh.

Nasa loob galing ang sound. Banda sa dashboard.

Parang ganito:

Okay nga iyan JDM na back up sound, minsan sa mga surplus trucks may ganyan pa. Hehe.

[dr. d]

Nasa loob galing ang sound. Banda sa dashboard.

Parang ganito:

from what i understand,
many japan-driven vehicles have them.
it's a common feature, in japan.
so when the surplus vehicle is brought into the country, it is sometimes cheaper for the dealer, to just let the beeper remain, rather than spend on labor to de-activate or remove them.

[Miles_on]

Yung Suzuki ko has a backup sensor. Dun sa flyers "backup sonar" pa ang tawag.

Despite the fancy name, it annoyed me at first. Feeling ko OA masyado because when I'd stop the car to manually check, I felt the distance to the obstacle was still exceedingly generous (malayo pa). I got used to it naman.

Ganyan na ba lahat ng beep sound ng reverse ngayon? Yung proximity na beep same sa mobilio pero yung steady beep beep, once lang sakin (isang long beep lang) pagkapasok mo ng Reverse.

Meron pa yung backup sound ng mga truck. Yung may babaeng hapon na nagsasalita.
