Do you really think it would take a long time to slow down from 75 to 55?.. and why are you guys driving 75 on the right hand lane?

I did almost get killed on the autobahn doing about 65.. but the other guy was doing well over 100.. I lost my right side mirror.

I commute 63 hilly miles (1500 feet elevation change) one way with my Leaf, with about 44 miles of it at 55 to 60 mph and 8 miles at 65mph. Charge to 100% at work and get home with one to two bars no problem. If you can charge at work, I wouldn't stress. The Leaf can do it pretty easy. :)

This kind of article we don't need.
The drivers here were idiots for driving their Leafs 65 miles one way without knowing for sure whether they could charge at this conference. The negative conclusions about the practicality of the Leaf are unwarranted, IMO. As stated repeatedly in this thread and others, the Leaf is not practical for everyone, but if you plan right or if you have an ICE car too, it is very practical for a driver with short distance driving needs. I've only had mine a week but so far no problems with the range.

As far as I am concerned there is a golden rule of traffic "Slower traffic stay to the right" If you drive 55 get to the right and be happy, if you drive 85 get to the left and be angry when someone slows you down or gives you a ticket, your choice (I don't care what you choose)

How many years do you think Leaf battery will last (i.e. degradation less than 20%) with 2 full charges per weekday ?
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

If he is leasing, he probably doesn't care... It seems like he could get by with two 80 percent charges, however...

Nope, I purchased, but I'm willing to take a chance on the range degradation. I'll be one of the first to look at for any battery dgradation. Even with a 20% loss in range though, I'd still make it to work and back. Hopefully by that time, an L3 will be around.

OK, you got me. As I understand it, both cases require you to accelerate some mass (in the minus direction) to a speed change of 20 MPH. Newton told me that with no force on the object it just goes along as is, and it doesn't even matter if it's relative to the ground or relative to the car I'm approaching. So please save me from taking phys 101 again and tell me what I missed. In exchange, I'll remind you that both the air and the road are standing still, which means my brakes will have an advantage at 75 (lots of regen) and my car will, also, with all that air resistance. Those would tip the balance, if the original proposal turned out to be a wash.
And there goes the first capacity bar! At 24,000 mi on 9/9/2013.
Second bar at 30,500 mi on 2/7/2015.

It is about the energy that must be transformed.

kinetic energy (K) = 1/2 mass * velocity^2
mass = Curb weight of a Leaf 1521 kg (3354 lb)

K for v of 75MPH = 854.9 kJ (kilojoules)
K for 55MPH = 459.7 kJ
Delta K(75-55) = 395.2 kJ

K for 20MPH = 60.8 kJ

K(75-55) = 6.5 * K(20)

Yes much more deceleration is needed to go from 75MPH to 55MPH than 20MPH to 0. Friction will be a bigger factor at higher speeds too.
