I picked up a 2017 SEL with Driver Assist a couple of weeks ago. Urbano Grey. So far a very nice ride. Averaging about 4.4 miles/Kwh (148 MPGe) and full charge reports 150 miles. I have an 80 mile roundtrip commute and am able to get to and from on a 90% charge with ~35 miles left on the range-o-meter when I'm done. I only charge to 90% and recharge at 20% to protect the battery.
If you get the SEL you have to get the Driver assist package - it adds all kinds of assistive features plus the digital cockpit from the Audi. The speedo cluster is one large LCD screen and it can be customized to show a variety of things. The quality of both screens is very good - they're responsive and high resolution. It adds $1395 to the price, but it seems silly to get the SEL without it. There are some other nice features. The LED headlights are sick; they light up the road like nobody's business and they swivel as you move the steering wheel. The seats are very comfortable and there are all kinds of ambient lighting options. There are no audio upgrades available, but the stock unit sounds pretty good. The main LCD screen appears to have some kind of proximity sensor: When you move your hand close to the screen, a row of buttons on the bottom expands. I've read that gesture based infotainment controls will be added; wondering if they'll make this upgrade retroactive.
The adaptive cruise control works well and is a joy in stop-and-go traffic. Just relax, point the steering wheel at the car ahead of and let the car do the work. It makes commuting so much less stressful.
The other assist systems are of marginal utility and don't feel fully baked. The emergency braking only works at very low speeds. I tested this with a large foam cube. Under 15 mph, the car stopped without hitting the box. Above that speed, it just plowed over it. Not sure what the point is. The lane keep assist is strictly for keeping you from going outside of the lane; left to it's own devices, it will ping-pong back and forth in the lane a couple of times before yelling at you, then finally shutting off, stopping the car and turning on the blinkers. The blind spot indicator is very handy, but sometimes gets fooled by cars one lane over. Twice now the emergency braking alert has gone off with no one in front of me (maybe that's why it's only active at low speeds - they don't want it slamming on the brakes as you drive down the freeway). The cross-traffic alert feature doesn't seem to work at all - I've never seen any kind of warning when waiting at an intersection or driveway; maybe I don't understand it's function.
The manual isn't much help and the sales reps at 2 dealers didn't know much about how these systems work. Worse, the capabilities of these systems seem to vary by region, so the youtube videos showing how the euro golf performs don't necessarily apply to US models. VW seems conflicted about the use of some of the features. For example, the manual section about ACC starts with a warning not to use it in stop and go traffic. Two pages later are instructions for using ACC in stop and go traffic.
Accelerator pedal mapping seems designed to get you to drive efficiently - you have to really stand on it if you want to move out quickly. It feels sluggish next to my wife's C-Max Energi, despite having a much bigger motor and battery.
Overall, I'm really enjoying the car. It's no Tesla, but it's economical, the fit and finish are top-notch and the ride and handling are fantastic.
