Savitar being Hindu god of speed is far-fetched, because not many have even heard his name. The sun before rising is called Savitar, after rising it is called Surya. The correct spelling of the name is Saavitr, S followed by a long A, as a in calm, and there is no a between t and r, nor a sound at the end, so that tr sounds more like tr in Trump, with soft t, no way as Tar. Others pronouncing the name wrong could be okay as it was a different culture, but the said god pronounces his own name wrongly in an imperfection.
