I don't think it is the cost of the car. A car company, like all of us here, earns a reputation based on many things and value is only one of them. Honda might have promised April and then met it or beat it - but, I don't think they would have missed a promised date. (Actually, they probably wouldn't have specIfied a particular day.). A miss would dent the corporate reputation, and that reputation is really important to them.
Addressing the delay will be important - so, Lucid, please let us know why the missed, self-imposed, deadline. Rumors and conjecture will stop and honesty goes a long way to cementing trust.
