It's an error. An error is a completely different thing to a glitch. As different as a cucumber and a waffle. I gave you the definition. Your description does not fit into any known correct use of the word glitch. Now, if you wish to continue this debate then first study English and the word Glitch in much further depth and secondly stop always resorting to a put down such as fanboy, butthurt and go cry. Always a sign of ignorance. You need to accept that you are wrong and by continuing to argue you are not doing yourself any favours. I've given a full explanation, a dictionary cutting with every example of correct usage and also supplied 2 in game classic examples yet still, you insist that low res' graphics are a glitch.
1. A sudden, usually temporary malfunction. Nope, its not sudden nor is it a malfunction. The vehicle still opperates as intended.
2. An unexpected setback. I've not witnessed any setback using that car (which according to you I don't drive), it drives and functions in the same manner as all others, as the game intended it to.
3. A brief irregularity. It's not brief, it's permanent which in turn doesn't make it irregular either.
So there you go, 3 perfectly reasoned responses to 3 dictionary defined examples of the word glitch and not one insult thrown. So, for the final time - it's an error.
