The use of telematics systems such as Green Road also encourages more efficient driving and I've certainly noted a lack of "spirited" driving in latter years.
This is an interesting point. Modern automatic gearboxes change up so quickly these days and don't seem to want to stay in a low gear for too long. I was on an E200MMC the other day and the bus was in 4th very soon after setting off.
When we had the Volvo B10M/Plaxton Interurbans the gear hold facility was regularly used on hills and I experienced some lively trips on them. Having said that, life hasn't been quite the same since the 6-speed manual fell from favour...
Is that the batch that had the 6LXDT engines? That engine was 12.7l as opposed to the 10.45l of the 6LXB/LXCT, so no wonder they shifted!
