Trinidad and Tobago going rhotic?

This video provides a rare opportunity to hear Trinidad and Tobago's TV ads.

You can here it in the background.

Instead of a typical Caribbean accent, you hear something similar to a standard Singapore accent.

Both Singaporean and Trinidadian Englishes are influenced by the presence of a large Indian community, so that's to be expected.

What's interesting is that there is also a commercial that has a rhotic accent in, presumably, an attempt to sound American.

Again, the situation seems similar to those of Singapore and Malaysia.
