General Driving & Private Joy. An Army of Mmmmm

Ya plug it in. Ya unplug in the morning. Ya drives. What could be simpler.
It's an Urban/subUrban Transportation Appliance. Mash the pedal and it GOES. Cornering is very well controlled. Brakes very well too. Everything 'just works' no muss no fuss no bother.
I plug it in every second or third day, unless I know there's a longer trip in store.
It goes from our base in Corvallis to Albany or Lebanon or Monroe without issues, or wanting more charge. Keeps up on the highway just fine. Fastest I've gone so far is around 75 and it handled that without issue. It just kinda goes Mmmmm . . along.

Here are the instruments as seen through the steering wheel, with a few distractions removed.
On the left is the Charge Gauge showing Six 'Bars' of charge (out of 16) and Gear status which is 'P' for Park. On the right is the Range Remaining (RR) display. More on that later.
In the middle is the digital speedometer and surrounding that is a big Ammeter gauge. Although it doesn's say 'Amps' on it, that's basically what it is. It's at Zero now (no surprise) and the Red needle moves to the left for re-gen (charging) during braking or coasting-in-gear and to the right to show how much current is being drawn from the batteries during normal running or acceleration. If there were numbered marking on the face the ammeter would show approximately 50, 100 and finally 150 Amps as the needle sweeps to the right.
Looking at the above RR=32 and Six bars of charge, you would reasonably guess that 16 bars (full charge) would translate into around 75 miles of range... and you'd be about right. The RR display functions by asking "How much charge did it take to go the last 15 miles traveled?" and then "If we assume we'll use up all the remaining charge at that same rate, here's how far we could go."
In the real world a full charge will get you somewhere between 50 miles (cold day, heater on and hiway driving) to maybe 90 miles in perfect (flat) conditions with no wind and a top speed of around 40mph. 'Normal' driving gets you somewhere inbetween. Probably closer to 60 miles than 80. Plus it's not a real great idea to run the battery flat on a regular basis. Leaving two bars on there is a good investment in battery life.
