That may be your reason, but the NEC doesn't require it. As the EVSE included with the Nissan Leaf requires only a 40A circuit, it is acceptable to install a 40A circuit with a 14-50 receptacle.

1) Our experience in California isn't very useful to the OP in Florida. Many jurisdictions adopt the National Electrical Code as is, but of course it is important to check for local amendments.
2) In California, jurisdictions can only amend the California building codes for "local climatic, geological, or topographical conditions," and those amendments have to be filed with the state. A list of jurisdictions that have done this is available here as a PDF: http://www.bsc.ca.gov/Rulemaking/LocalC ... ances.aspx Are you aware of any jurisdiction that has amended the California Electrical Code to prohibit a 14-50 receptacle on a 40 amp circuit?
3) Misinformed inspectors making up requirements is always a problem.
