OK, let me see if I understand all this correctly.
A Republican Senate in NJ has done something evidently unjust on behalf of a Car Dealer Association, placing the interests of a hated special interest group of salespeople ahead of the interests of the citizens of New Jersey.
In so doing they have got to first base at the cost of raising the anger of a large crowd. Most curiously they have done so in the absence of any high power representation from Tesla or any big money legal intervention, again from Tesla.
...BUT... Getting to first base counts for squat, because the deal needs to get through a Democratic legislature to pass into law.
Now the battle that matters can begin, Tesla can roll out the big guns and do so with a tidal wave of public support to right an injustice. This Tesla is bound to win in the Democrat-led legislature.
...BUT... The Republican governor has a veto, which on any given week day he can use to overturn the decision of the Legislature as he sees fit.
...BUT... This Governor is a Republican Presidential candidate nominee hopeful. The will of a huge groundswell of angry citizens who do not want to have their rights as consumers shunted for the benefit of some car salesmen is not an attractive target to veto.
...AND... Without going through the process of getting everyone all riled up about the original injustice, that veto would have been much more of a danger than it now is.
End result - Legislature overturns anti-Tesla provisions, perhaps even adds a clause to ratify Tesla's rights to trade. Governor does not veto the legislature.
Does that sound about right?
Sadly, I fear that no, it does not, Julian. This Motor Vehicle Commission is a regulatory authority, not a legislative sub-body. So it is not a legislative statute that came up today; rather, an authority's edict. Not directly up for the legislature to rule upon...and thus also not something the Guv can take his veto pen to.
So....although by the time the fat.........lady........sings, there might be something for the Tesla community to cheer, it won't be via that path you enumerated.
