Each person's situation is different, but here is my perspective.
I am choosing to lease primarily because I love the car and am excited to drive it, but I am not totally sold on Tesla's commitment to servicing it properly over a long period of time. This, along with the lower monthly payment has led me to choose to lease.
Regarding the terms and their relative reasonableness, I look at it this way.
If the residual is below market, then in fact you are purchasing the vehicle using a manufacturer-sponsored, "low up-front" financing plan (and willing to pay that acquisition fee for the privilege). At the end of the term you wil either be buying, and keeping the car, or (unless one wants to lose easy money) buying and reselling the car. In this scenario, it seems to me that the only pertinent factor is the interest rate as it compares to simple loans in the larger market.
If the residual is above the market, then you are paying for use of the car for a specific term, and all other things being equal (tax, registration, etc.) the pertinent factor is the monthly cost, however it is calculated. Even if you like the car and want to keep driving it, a decision to keep it at end of term would be emotional, not financial.
Since Tesla is not offering an option to purchase at the end of the term anyhow, I look at their lease terms strictly to see if the monthly fee is reasonable. As I am not aware of any other realistic lease options for comparison, and taxes/registration have to be paid one way or another (and the acquisition/disposition fees are actually pretty reasonable, compared with other manufacturers) I set my eyes on that money factor/interest rate.
At first look this is very high, 5.45% on my screen. However, the residual is also very high, it calculates out to about 67.8%. Obviously this is irrelevant to any future purchase, but it is very high by industry standards, and arguably also by any realistic future prospects. This greatly affects the amount amortized versus simply borrowed, and thus the actual cost of the lease in dollars.
For example, instead of 5.45%/67.8%, how does 3.25%/62% sound? A lot better on the interest rate, and much more likely on the residual side (although still a bit generous, in fact). Well, it comes out to almost exactly the same dollars, and for me, since I prefer to lease anyhow, and I figure if I still love Tesla I will be able to buy this or another car at the end at then-market price, that dollar/month amount is all that matters, and in fact the deal is not in my view so unfavorable at all.
YMMV, naturally
