I would agree with Sal say it
I would agree with Sal say it's a bit misleading and an apples to oranges comparison. The 30 in "30-minute chargers" is arbitrary. To make it more accurate, Tesla has 12-minute chargers, vs. Nissan's 30-minute charges, since that's about how long each would take to add 60 miles of range.
Also, the article makes a strongly inferred comparison with Tesla, stating, "As Tesla Motors ... [accommodates] long-distance driving, Nissan focuses on ... everyday driving." But this is another apples to oranges comparison, since it doesn't explain that with a Tesla there's no need for a charging network to support everyday driving.
Overall, it doesn't read as a balanced article.
