Returning to Brendan's original post about pride in the job: There may be a technical reason for the inconsistency in the position of the reflectors, though like Brendan I suspect it is complacency either by the designers or the workforce.
I had cause to show how such lack of care could affect the sale of a product: A company I was called into had a production lines which from had a different work force depending on the shift. It was common for the product from both shifts would appear on the same sales shelf in the retailers. I obtained two samples from a shop and returned them to the company to demonstrate the differences.
The designers had made an indentation in a plastic moulding to accept a self adhesive data label. On one product the data label was correctly aligned and positioned fully within the indent. The other product had its label incorrectly positioned, It was slightly twisted and not sat fully within the space provided.
When these two products were put in front of the companies MD, and he was asked which would he choose, he selected the neat one, as did virtually every other employee, including the shift workers.
Hall testing of the issue revealed that where there is choice of the same product, appearance is one of the most important differentiators and a well turned out product has as much as a 85% chance of being selected over a less tidy product.
I also had to point out to the company, that in this particular case, the standard to which this product had to comply actually requires the data plate to resist removal by abrasion, so the incorrectly placed label was not actually compliant as the one edge of the label could easily be picked and start to peel.
The same effort was needed to apply the label, it was just carelessness by one shift operator, plus the fact that they did not know why it was so important from both the aesthetic view but also the legal implications. It took just a moment to advise the worker, and the problem was resolved.
I will often criticise the caravan manufacturers for using piece work contracts for their production operatives, Sadly this was the type of employment used by much of the British car industry and look where that ended up. Now look at the remaining car makers, where the employment has moved to quality circles. Piece work employment places more emphasis on quantity rather than quality
I have no doubt that a workforce kept informed of WHY a particular feature is important, is better motivated because they feel more involved and responsible and thus valued. There are plenty of companies who employ by the hour that can match the effective output of pieceworkers, though the numbers rolling of the production lines may be down slightly, there are less faults that require product returns.
