It has electric brakes, right?

It has regen, which is basically energy capture via electric brakes. But it also has regular breaks, most drivers don't use them much so they last a really long time.

How does it work? Does it use regen exclusively if you press the brake pedal lightly, and then the mechanical brakes are only engaged when you stomp on the pedal, or?

What sort of maintenance are performed on these cars?? Seems like there is nothing to be maintained, given the all steel, aluminum, glass stuff everywhere. Does it have any oil changes required, like in brakes or transmission?

Break fluid, battery coolant, drive unit fluid, tires when necessary, wheel alignments when necessary, wiper blades when necessary, key fob batteries.

If everything goes right, Model 3 can change the business model of cars. Shift to value add + functionality upgrade based pricing versus a sales and service oriented model.

Also they own the repair market. You can't get your tesla serviced at a normal shop as the software, parts, and diagnostics are proprietary, so they could actually sell the car at a loss and make the big bucks on repairs. I don't want this. But its a viable business model.

Actually this is the way most manufacturers already work today. That's why they are so slow to shift to electric - less spare parts.

I'm certain if I ever own a Tesla, it'll be a long way into the future. I'm glad they keep pushing forward though, it's causing the infrastructure to advance to a point where I'm almost ready to go fully EV. Where I am, a low-mileage (20-30k) 3-5 year old Nissan Leaf is the equivalent of around $12k with no road tax to pay. And it gets around 150mpg equivalent due to electricity prices. Exciting times!

The Nissan Leaf is a terrible EV. The 3-5 year old models you mention have very low range (~60 miles). That's why they're so cheap. People that own them are constantly mindful of their charge % and are always on the lookout for charging stations if they're deviating from their normal commutes. I've seen many of them run out of juice on the leftmost lanes during commute hours too, causing even more congestion for miles. If you were looking at new cars, you can get a 2017 Chevy Bolt with 200+ mile range for not much more than a new Leaf.

Never really understood the "luxury" interiors with huge number of details, materials, mixes of leathers, wood, different kinda of metal, etc. The interior that stood out to me was porsche 911 from around 1970. Not distracting, simple, robust, and lasts 30 years (when I saw it). A larger display for excellent situational awareness (map, gps, dozen or so cameras, ultrasonic, and radar). What were you hoping for? A few…

Touch screens are terrible to use while driving, especially for frequent operations (volume, change stations, climate control, hazard lights, wipers, etc). The current trend is to push more into these touch interfaces, but most car manufactures have still left some of the more important ones as physical buttons. For tesla the matter is not ergonomics, but simply cost.

"terrible" seems overdramatizing. "Slightly inconvenient at first, but fairly convenient a few weeks down the road after the muscle memory develops" is a more apt description. Volume and wipers have been duplicated to steering wheel knobs and levers, hazard lights do have a physical button (as electrical system failure and touch screen outage are a possibility), and climate control defaults to the last desired temperature (and that's if you chose to go off auto).

I really hope the German government does something to make it more desirable for employees to want the Model 3 or similar cars as company cars.

Just to explain the involved costs: There's two ways the government taxes company cars for employees, either you get to write a driving log, that then marks each route as either private or business and then you get the privately driven part taxed as income OR you just get 1% of the new car value taxed as income each month and don't have to provide a driving log. The company pays for leasing, gas and maintenance.

That's where electric cars savings on fuel and maintenance don't affect business customers, they don't care mostly because the company pays for the gas anyway and is used to do that so it will stay that way quite a while.

I just hope they give a tax break on the 1% rule, so it's just 0,5 or something similar that makes these cars more desirable compared to a similar priced gas guzzler.

Yes and no. The low use of the brakes can be bad in non optimal weather, and can lead to the brakes getting stuck, uneven etc. There has been some problems with this in Denmark and Norway. So you still need to service the brakes.

It depends on settings, state of charge and temperature of the batterypack. On normal it stars a slow regen as soon as you let go of the "gas". And brakes are only deployed if you hit the brakes. However if you already have a full battery (very rare) or the battery is cold (very often in cold winter) the battery cant absorb the charge, so regen is disabled. This means the car brakes very differently, with or without regen, but this is also indicates on the dash.

Connects the wheels to a generator to recapture some of the energy. Slows the car down too. Good as a "first level" brake.

Is there a HUD or do I have to move my eyes to the centre console to check my speed? Seems like bad ergonomics to me... and whereas the road ahead is perhaps still in my peripheral vision when I check my speedo, its less so if I am glancing at the centre console (which maybe has a bunch of other distracting things on it as well?)

Elon mentioned the interior was redesigned with full autonomy in mind. I guess the use case "driver maintaining the vehicle speed via non-autonomous pedal pressure while wanting to check the vehicle speed because he did not enable cruise mode" is a weird edge case for them.

On autopilot the car will stick to the assigned speed (with adaptive cruise control slowing down or speeding up depending on the traffic in front of you). In fully autonomous driving mode the car will read the speed limit signs and adjust.
