I think the business model will have to change for this barrier to disappear.

Most likely in the future you will buy or lease the car. But you will never buy the battery only lease it.

When the battery is fubar the manufacturer will recycle or resell for utility storage and replaces your battery pack.

Much like Auto companies went into Financing business to boost sales they will likely go into Battery management businesses to boost sales.

I can't see another way for long term.
