This made me curious to do some Excel calculations on a race between a Tesla Roadster and a Nissan Leaf.
If you assume that the Roadster has a 70A 240V HPC available exactly when it wants to stop ( about 180 miles by my calculations )
And the Leaf has a Level 3 charger available exactly when it wants to stop ( every 70 miles by my calculations )
I also assume that both cars will travel at 60mph ( note that they could actually get a better overall time by driving slower ).
The Roadster will charge optimally according to the numbers from Tom's calculations ( up to about 85% - full standard charge)

The Leaf will take 30 minutes to get an 80% charge from the Level 3 charger.

Both cars stop to charge when they have about 5 miles range left.
And I assumed a 15 minute penalty on a charge stop to ( get off the highway, wait through a light or two, pull into the charge station, plug in, leave the charge station and get back on the highway )
There is some sawtoothing happening because of the different pitstop strategy, but obviously on your last stop if you dont need a full charge you cut it short.
Up to 70 miles its a tie when the Leaf stops for the first charge.
Up to 180 miles the Tesla wins handily.
While the Roadster is on its first charge stop the Leaf will briefly pull ahead.
At about 360 miles the Tesla is still winning but its not a big margin.
And at the 540 mile mark its a tie when the Roadster pulls in for its 3rd stop.
The Roadster manages to complete a 540 mile journey with 2 stops at 37mph
The Leaf manages complete a 540 mile journey with 7 stops at about 37mph
Once the journey is longer than 540 miles the Tesla falls further and further behind.
Considering that 540 miles in a day at 37 mph is a lot more than anyone wants to do, I think the Tesla is a better car for long trips when optimal charge infrastructure is present.
But the Leaf can complete this particular 483 mile trip pretty easily in 13 hours.
