With my Texas drawl, it’s basically “vee-icul”, but vehicular is “vee-hicular”. No real strong stress on any of the syllables.
I would’ve sworn that Boss Hogg was a whole lot fatter than that. Huh.
For me, the “h” kinda slides (or elides?) into a “y.” Like VEE-yickle. But the stress on the first syllable is very light. It’s an unvoiced “h”, but functionally it sounds like a “yuh.”
I’m with @Smapti . I’m American too.
I associated vee-HICK-l with a more hick accent, so many around me say it that way, but I say VEE-uh-kl.
I do notice that that k is unaspirated, and possibly released glottally. Huh.
I don’t normally pronounce the H in “vehicle,” but I think it’s a legitimate pronunciation variant.
I would pronounce the H in “vehicular.”
Well, by 1970s standards, he was pretty fat. By 2020s standards, he’s just a bit overweight. 
Not necessarily, could just be light aspiration? The defining feature of the glottal stop is the rapid close-open of the vocal folds; we’d have to hear @Kent_Clark pronounce the word to know whether he’s doing that or just semi-aspirating the H.
I don’t hear a glottal stop, which isn’t to say that some people don’t do it. In my ears, I hear the ‘ee’ sound sliding into a ‘y’ sound and from there to a schwa.
Same here. I do want it clear that it’s spelled with an “h.”
You may be right.
Note, however, that aspiration is something ascribed to plosives like a glottal stop, not to fricatives like a /h/. So if we’re talking about aspiration, we’re already talking about a stop.
I wouldn’t be shocked if some people used a combo stop-fricative like /pf/ or /ts/ which would be even harder to distinguish as glottals.
I’m not an expert in those terms, so call it whatever you want. The only way I can describe it is, I don’t pronounce it “hic” and I don’t completely eliminate the h so that it comes out “-ic.” What comes out is a “(soft exhale)ic”
Yeah, if there’s any sound at all, I would still analyze it as /h/. Consonants can be softened. And ultimately /h/ is just any unvoiced vowel.
One thing I learned as a vocal major is that, if your breath makes any perceivable sound, it is caused by some sort of vocal tract restriction. A totally unrestricted breath is perceivably silent.
I wonder if your accent might actually partially palatize /h/ before that vowel in hic. That would make a clear distinction for you between a hard and soft /h/. It would be similar to the h in hue, and would have a stronger sound than the /h/ in, say, happy.
oh, and as for the other part: I personally am okay with using aspiration more generally for audible air, so I will say things like “aspirated vowel” instead of “devoiced vowel” (i.e. /h/). I find the idea that aspirated mean “aspirated release” (as in a plosive/stop) to be a bit restrictive. The consonant /h/ is produced with an aspiration of air.
Philly: Not even a trace of h. But there is an h in vehicular.
Now there’s an odd one, because for me “vehicular” starts with a “veh” not a “vee.” And it does have an “h.”
Grew up in Upper East Tennessee. I pronounce it VEE-hi-kuhl.
Same (but I’m in the northeastern US).
I highly doubt that people across the US started pronouncing the word in this fashion just because a TV show that pulled in 40 million viewers weekly included it. People in the south already pronounced it that way to begin with.
In ancient Greek: Vee-Hih-Clee.
Yes, and all around the rest of the country millions of little boys were chasing each other on their bikes yelling “You scuffed my veehickle!”
Vee-HICK-ul
