There shouldn’t be significant differences in most states’ fees, taxation, etc. between leasing and financing (in the sense that any complexity in financing difference is likely no worse than leasing differences, for a company with Scout’s resources).
If I were a new EV company, I would be worried about initial depreciation (which, if I set high residuals means I would likely eat the losses, and setting low residuals might not generate enough leases or lease revenue to matter).
More importantly…leasing is a demand lever. Unless you’re setting lower residuals to ensure the ability to resell at a profit (or not-a-loss), it makes sense to do what Rivian did and wait until the early adopter rush dies down a bit. And a lower residual reduces or eliminates the value prop of a lease for the consumer.
As long as folks are paying cash or traditionally financing, I don’t have to:
a) worry about eating depreciation losses
b) stand up leasing infrastructure, including the entire end of lease process (vehicle turn in, inspection, and either used sales or auction- noting that used sales are a whole can of worms that most manufacturers don’t want to deal with)
c) worry in the slightest about reconditioning or rehabbing an off lease vehicle
When demand starts to wane a bit, and there are indicators of consumers wanting lower payments, I can start activating a lease program to capture them.
This also means I have time to assess depreciation on my brand-new-to-the-market vehicles and make informed lease terms.
It
also means I have time to start standing up lease turn in and disposition infrastructure, which isn’t all that trivial.
Of these, the demand lever/depreciation assessment are probably the biggest factors.
All that said, I’d like to see a lease option at launch

Edit to add: has anybody been tracking Rivian 2-3 year depreciation? I feel like it was worse the first few years and has stabilized nicely
Here's what Car and Driver posted about depreciation after driving a 2022 Rivian R1T Adventure for 40,000 miles.
