At least for me, it's not about souping the car up, it's about doing repairs and maintenance myself because a) it's cheaper and b) it's more convenient. If I knew I was going to have to drive a car to the dealership anytime something went wrong, I would not buy that car. It's a big hassle (especially if the dealership is any distance away) and almost always outrageously expensive for anything outside of warranty. And…

Among many, many other models both in and out of production, Teslas are not the best choice for hot rodders. Got it.

You don't have to be a car mod enthusiast to have a desire to use a business you trust and have a good relationship with to repair the property you own.

But think about it from another perspective: someone purchases Tesla car, decided to service it himself without sufficient knowledge, then later he resells his car to another individual, the person who buys his car enables the autopilot mode on a car and because of the poor service quality/mistake the original owner did to a car the autopilot goes crazy and steers your car into a brick wall, everyone will blame Tesla…

You simply can't enable Autopilot if the car is produced before May 2015, because it is missing the required hardware.

Funny thing, you get down voted here on HN for facts it is against Tesla.

> A lot of Tesla fans claim that electric vehicles are inherently superior, because with fewer moving parts, they'll be able to stay on the road basically forever - no piston rings to wear, no transmissions to fail, no oil to change. There are at least two major components that "wear out" in power electronics - capacitors and power transistors. Traditional vacuum-impregnated motor winding insulation also has a wear-o…

I found your addition very interesting. But I think the "Tesla fans" referred to, are referring to something different. The Tesla vehicles are "missing" a lot of parts that rust, corrode, and cause engineering challenges. One of the main ones behind the exhaust system. Speak with a series of car mechanics and they'll invariably tell stories of cars that never received an oil change until something fails. There are vi…

I have an 89 Ford. It has been parked outside in rainy Seattle for 20 some years. Other than the exhaust system, it is free of corrosion. I find this rather incredible. Ford has done a truly amazing job with corrosion protection, unlike my older car which rusts when a cloud passes by.

I also have to compliment Ford on building a low maintenance vehicle that is also cheap and simple to repair when it does go wrong.

This article is spot on, but the author fails to account for the fact that on _most_ new cars, your in the same boat. Unless its a maintenance item, your not going to be able to replace it with anything but the manufacture's blessing. The biggest difference is there are a lot more maintenance parts on a conventional car, so you have more of an opportunity to replace things. It was my understanding that the only true…

> It was my understanding that the only true maintenance part on the Tesla was the wiper blades. And the brakes / tires.

And the HVAC system. I don't know but wouldn't be surprised if the HVAC system on Teslas, in addition to the cabin environment, had some responsibility for the battery and motor thermal management too.

Expensive is different from "can't," and there's definitely one company whose mechanics can replace the battery.

It's all about ROI. You can make a case for almost any conventional repair, save a transmission or engine overhaul. When a battery replacement exceeds the value of the vehicle, and the one source of mechanics is incentivized to sell a new car, the economics will never make sense.

Much will depend on exactly what batteries cost in 10-15 years, or whenever the current batteries start to fail.

If they still cost $25,000, then yeah, that's probably going to be a poor value proposition.

If they cost, say, $5,000, then no problem!

If Tesla and others start selling ~$35,000 cars with 200+ mile ranges in the next couple of years, then I think it's going to be closer to the latter scenario. But it's hard to know for sure.

One of the things that makes a car valuable is having a healthy aftermarket. It looks like, from this article anyway, Tesla is doing anything they can to make sure there is no aftermarket for their vehicles. To me, a car that you can't service yourself is worthless. A car that needs the manufacturer's permission to activate is not your car--it's owned by the manufacturer. And, when the manufacturer places a threateni…

Of the handful of people I know that have bought Tesla's, they are very much not of the hacking mindset. I'm not saying this is forever true, but I think the type of person that can actually afford one usually has the "premium" and "executive" mindsets (if I can makeup some terms). That is, they'd rather pay extra for 98% of everything they want and not have the worry of needing to get their hands dirty (the premium mindset). And if there is a problem? They replace/trade-in/buy more premium services to get what they want. They have "their people" take care of it. These aren't intended to be negative descriptions, but more of an informal observation of how people in executive positions with resources available tend to prioritize their time and effort. But of course you'll eventually get more hackers drawn to the car in time.

I feel the same way. I drive a classic Range Rover, and it is a lot of fun. Yes, I spend around $2000 each year getting various components repaired or replaced, but that is enough to keep ahead of entropy, and between loan payments and the higher cost of insurance I'd be spending twice that or more on a newer vehicle. Plus, I have a relatively simple machine with no fancy DRM automation crap that won't report me to t…

Apparently you're 8 times more likely to die if your car is half the weight of the one you have a high speed collision with (sorry from memory no reference, could be bogus). Add to that the over-the-top strength of the Range Rover and even though it's a classic, I think you're going to be more likely to survive in a head on collision than 95% of other vehicles on the road.

That makes sense in a simple, back-of-the-envelope F=ma sort of way. I hadn't really thought about it from a safety perspective, though; it just suits my needs well. In general I'm happier to economize by buying really nice stuff that's cheaper because it's used, than by buying something newer that's just cheaper. It becomes an aesthetic thing - a feeling of shabby luxury suits me.

I don't care to own the car. From my point of view, it's a service I want access to, to get me from point A to point B. Tesla makes that process enjoyable.

Because Tesla leveraged software, like an app, I want Tesla to handle the updates for life of the car.

Here in Lisbon no such distinction is made, any diesel or gasoline car built before 2000 is banned from the city center.

Wow that's very interesting, I didn't know that. Although going by year is a little arbitrary (a 1995 honda vs a 2005 GM SUV?) I do support the concept. Personally I'd like to see most city centers car free.

I agree that the cutoff by year is somewhat arbitrary, though SUVs have never been popular around here, with gas being so expensive; right now, it's at ~1.36€/liter (aprox $5.67/gallon), while our median salary is less than $1600/month.

I don't think things are as dire as he makes it out: 1. Small amount of cars on the road so there's limited incentive for aftermarket parts. 2. People already do brakes/tires/suspension/etc. It's a car after all. 3. I wouldn't want to get near the powertrain. 425kw(~400V @ 1,000 Amps) will kill you if you touch something that you shouldn't. I think it'll be a bigger issue once we see the Model 3 on the road.

Your computer power supply has a ~400 volt rail in it. Are you unwilling to ever open a desktop computer? The Tesla battery has contactors inside of it, so you'll only have 400V live when the car is on. Additionally, assuming the HV is floating relative to the chassis, you need to touch two spots at different potentials to actually get shocked. That said, it looks like this is an attempt to prevent service of a lot o…

Not at 1000 amps, it doesn't ...
