I'm at Mobile World Congress in Barcelona and just had an interesting conversation with someone at Volvo heading their connected car offering. The reason LTE is not available yet (even though some manufacturers have announced it - he shook his head at this) is because there is no LTE chipset certified for automotive applications. They don't expect a certified chipset commercially available until late 2014 (November, maybe). So until then, it's 3G (HSPA) and FauxG (HSPA+). He also reiterated their view that 3G "is enough; 1-2 Mbps, roughly". He also said consumers aren't really asking for it, but marketing is driving the request for LTE ("another sticker on the box"). So there you have it.
