Why long drives in automatic cars may be dangerous for you

[omega44-xt]

I think that you are talking about the taycan turbocharged one. Yes it has a gearbox but not like the traditional ice cars. The model s's latest ota update has raised the top speed to 160+ in ludicrous/raven mode.

But still at cars are catching up with the mt cars here.

Tesla used software to limit battery capacity & power output for lifespan reasons. Once they got more data on battery degradation, maybe they were fine with increasing power & still have a good battery for 8 years, their warranty period. Also I read somewhere that Tesla quotes lower range numbers than the one they got in EPA tests (US alternative for ARAI), as those tests usually result in 10-20% higher figures. Same can be said about kmpl numbers here in India, if you get a mixed FE of 20% less than official figures, you are good.

AT is superior to MT, especially dual-clutch ones. They have a manual mode, paddle shifter usually, so that's what most sports cars have it. Don't put AMT in same class as proper AT. I drove AMT a year ago, it wasn't a great experience, slow gear changes were annoying. But its surely cheaper, at about 40k premium or so, and definitely convenient in cities even if not so responsive. Didn't try it out in manual mode.

I disagree. It really depends on the particular gearbox in question and the application. Volkswagen's DSG is great, but Mercedes' torque convertors are just as good.

In normal city traffic conditions in this country a DCT will likely be worse, because 1. the gearbox is heavy 2. in stop and go traffic you don't want to feel the gear changes

Yes I agree.

Automatic cars are most comfortable to drive specially in City traffic, and all of my friends who have AT suggest me using one. Obviously, they all have one reason of No shifting of gears manually.

Yes, falling asleep can seriously cause accidents, Last week I went to RTO for driving license and they were constantly showing Ads on TV regarding reckless driving and falling asleep was one of them.

You will not believe me when I'll tell you that my friend's friend had such accident where he had fallen asleep while going home on his BIKE....he just crashed and got so many fractures in hand and legs was bedridden for weeks but luckily escaped death.

How is feeling gear changes relevant? Even in MT you feel it, moreover, have to do it yourself. Gear changes were good enough in DCT, CVT & TC vehicles that I rode, not sure I ever rode a DSG one though. AMT ones were the worst IMO.

Most AT would likely be heavier & you will get a bit inferior FE, but not drastic, maybe upto 10% less in real life.

Nowadays ATs actually consume fuel more efficiently than MTs. My Honda City burns more fuel than my Hyundai Elantra. The former is a 1.5l MT and the latter is a 2.0l AT; both petrol.

The points about gear changes is when comparing TCs and DCTs, not MT and AT.

Also feeling gear changes is relevant because of sudden changes to acceleration, which your body can actually feel. In normal operation a torque converter will mostly smooth it out, not unlike CVT, but a DCT's snap may be more noticeable. Also the point about heaviness still holds because DCTs are usually heavier than TCs for the same numbers of gears.

Again this all depends on the gearboxes in question. The difference isn't huge.

Debates like these will be irrelevant once Tesla launch their robotaxis in about 5 years. The future is autonomous fortunately or unfortunately,.

Model S is >8 years old and India still doesn't have any of them. Bulk of electric vehicles in India are Buses, taxis, auto-rickshaws and low power two wheelers. Govt. hasn't made it cheaper for public to own any good electric vehicle. Oil corps have lobbied against electric vehicle reforms. The subsidy schemes are not applicable on vehicles meant for personal use IIRC. Future is autonomous but India needs another 30 years to catch up (maybe even more).

Brother I was not talking about India but the industry as a whole. Yes the Model S is 8 years old. But do you know the tons of difference in the body/features/ota/battery that are between the Model S of 2013 and Model S of 2020? Heck do you know the differences between the Roadster 2017 and Roadster 2020? Man that ludicrous mode is insane. A million miles warranty on batteries? And they are not some excide or amaron batteries but Tesla batteries. Tesla has already mastered Level 4 of Autonomous driving, level 5 will be achieved in the few months. Do you know what plans Elon has? Since last year all Model 3 cars are coming with full autonomous driving, previously one needed to pay more money, but they would be locked via ota. When the US government allows level 5 AD, Tesla will ask users whether they want to use their cars as a taxi to make more money. Even if a person has taken the car on loan but the car is paying for itself, so do the math. VW is also planning the same. This will kill companies like Ola and Uber. These companies have also started piloting AD in their vehicles btw.

Coming to India, Model 3 will be imported as a CBU from China starting from this year. Now what you have mentioned is also true. Oil companies can't do shit as even the biggest of them all Aramco knows what the future is. Subsidies of 1.5lac won't help at all. The companies also need to give better options. What is extraordinary in a Kona, MG EV compared to the price point? Nothing. Tata's ev is fine as per the price but not good. As the government has said that they won't register any ICE vehicle after 2030 and the companies are also upping the production of EV's but most importantly the customers are also willing to buy the ev's. So, I think with the introduction of Tesla, ev's will be mainstream by 2030 but not AD ofcourse. Commercial vehicles might take another 5 years.

They will need a platform to let users know that cars are available. Fragmentation into manufacturer-owned platforms will not work. They are more likely to tie up with Uber or other ride sharing/cab aggregator platforms to tap into an existing market. Especially in places where taxis are highly regulated but cab aggregators are not.

Tesla for one isn't gonna tie up with anyone. Their AP is 10 years ahead of everyone. It is even better than Waymo. VW might but I doubt that they will. Companies like Rivian might but again that's just a speculation.

Which Gearbox you will prefer to buy ?
1. MT
2. AT
3. AMT
4. CVT
5. DCT

DCT > CVT > AT (torque converter?) > AMT > MT

I think pricing is like that as well. Drove AMT once, didn't like the shifting, but if I end up in top 6 cities, I might get that. Price is an important factor though.

DSG(Nothing beats this), then CVT and then I would select something like an ev, hopefully Tesla but budget issues. The rest are all crap.

So, Fuel Consumption is also lower in DSG/DCT ?

Fuel consumption depends upon the engine capactity i.e. cc, weight of the vehicle and in which mode/how it is driven. It has nothing to do with DSG.
Just drive an AT vehicle with DSG and you will feel the difference.

Not quite. Fuel consumption depends on a LOT of factors, not just engine capacity.

Please list those other factors and enlighten us. And I have mentioned few others too besides engine capacity.

Sorry I missed this earlier. Yes they do. But now their cars are coming with a million miles battery warranty. I think that's enough.
I am not putting AMT in AT's class. Just meant that even an AMT is better than the manual one's.
